I can only imagine turning to that 300-year younger kid & saying "when I was your age, Pluto was a planet"
pluto was never a planet, but it will always be my favorite stellar body.
JG R that can happen in 5 years
+ninjamanfu - Pluto was and will always be a planet. Its like telling a person who's been around for 70 years hes no longer a person as he/she is too short!
They made a mistake when Pluto was given Planet status, and it could have been justified to correct it after a few years - but not after 70.
Danny Rosenberg damn
+Evol Bob a person is always a person, no matter what size they are, but collections of particals in space are classified directly by size, density, ect. midgets are people, pluto was never a planet.
My greatest fear is not living long enough to live forever.
Ghrey there's cryonics to answer this problem.

This channel is criminally under subscribed.
Vladimir Yuriev Very true
Yes it is but the comment section is fantastic.
I advertise it with some regularity.
indeed
I agree Vladimir. And I just stumbled on it by chance. Now I can't wait till Thur. comes around to get my 'fix'. ;-) After finding this I had some serious binge watching to do.
Being "bored with life" sounds a lot like a common symptom of depression. Depression is somewhat treatable, and treatments are improving over time.
I'm a young person, so ultimately idk, but I feel like a lot of people would still be able to find things to do with their lives. I feel like a big reason people IRL become tired with old age is due to deterioration of the body and mind, but if that can be eliminated then would someone who's 200 years old but still look 20 have the same energy and vigor?
@@pancakes8670 well put. The key is a healthy body for the mind to inhabit. That makes life enjoyable.
I actually find it interesting how most people, when being told of immortality, get to a point where they say you'd be bored of life, and you'd see your family die and everyone you know die. However, what if it's by choice?
@@Nedia___ That also assumes that it’s ONLY you who’s immortal. If even 1% of your species ever chooses true immortality, wanting to see the end of time or whatever, then that’s plenty of friends or family you could never lose. Maintaining friendships over that long may be difficult, but if you live forever then you have forever to mature and get over any distances, and forever to stew over them first if that’s what you want to do.
And assuming we can even be immortal, then it would be by a process we can reverse if need be, depending on how it winds up coming abt. It also means that we will have people who are NEAR immortal, the ones who would have taken all the serums or implants that let us develop immortality pills or whatever.
I’d want to be at least quasi immortal, living billions of years, because I want to see another species, or if I found them in their neo lithic period, leave a Safe on one of their moons with my number, who I am and why I left it there, an explanation for the Fermi paradox if we find it, and a guarantee I’ll leave them alone if for whatever reason they don’t want to hang out.
I’m willing to wait however long I need to in order to do that, but since my own life will likely be limited, I just hope someone else in the future Carry’s the torch I could never pick up
Live forever or die trying. Amen to that
It's a goal that will never fail.
you could make a religion out of this.
if i would achieve immortality, my life would be complete and i could die happy :)
If we support longevity research then it can happen, it is currently underfunded but with more awareness and support there is a chance you could achieve immortality and die happy :D Anyone who is interested in this can join a longevity discord channel (discord.gg/ftSbffu)
Zamuroy what about people who have died before this technology u would miss them and what about getting married to one person for 300-400 years
Yeah we must donate to SENS
Aust, dying before the technology would only apply to some people in the first few generations. They will just have to live with it.
*"what about getting married to one person for 300-400 years"*
What about it? If the 2 of you are happy, so what? If you aren't divorce.
ExtantFrodo2 well, they will have to not live with it if they are dead before it exists
edit: after revisiting this video after 9 months, I have noticed that I forgot a comma.
I'm beginning to really enjoy Thursdays.
I'd be happy to live thousands upon thousands of years.
The movie "The Man From Earth" touches heavily on this topic.
It was a good film, especially considering the budget, practically a textbook example of how to do a scifi bottle episode right
sequel coming soon
I was thinking about that movie as well. Great movie and I was thinking specifically about the part where he mentiones he had the same degrees as all the other professors, just a bit out of date.
Another reason you will never get bored in life. The world changes fast enough you will never have seen it all or know all.
@@isaacarthurSFIA I'm betting that almost everyone who wants radical life extension doesn't want to spend centuries or millennia as crippled elderly people with kilotons of health problems, but want to spend that much time living as healthy, younger people.
After all, what good is radical life extension if you're existing as an elderly with many health problems.
I think that's one of the concerns.
I went to look up this movie and found it for free on prime and I am now watching it! And I am loving it so far, thanks for mentioning it.
I'm taking this as my "how to roleplay an Elf" guide
Wait till you get to the part about Slaanesh.
That's an eldar.
And the eldar is a race of space elves. This channel do a lot of space stuff. Btw, where do the eldar belong on the Kardashev scale? ;) Or Slaanesh (Insane homicidal god of lust) itself? :P
Ok. Id rather live long enough to marry an eldar. That is if Space elves even exist.

This guy is brilliant! You think a guy with a speech impediment would be presenting a show like this on TV? Not in a million years! All Hail TH-cam! All Hail Isaac Arthur!
I wouldn't be surprised to see Isaac doing TV narration someday, and commanding a hefty price for it. His youtube content is compelling, and his speech impediment is a pretty big branding hook. If he keeps rocking it like this and getting more exposure, the unique sound of his voice will one day be synonymous with science (it already is in my head).

The whole Immortal Depression thing, I think, tends to be formatted around characters who are immortal when no one else is. The sorrow comes from watching everyone you love die, and the depression from them not being able to connect with anyone else (either for fear of losing them to time, or from no one being able to GET them).
In this scenario, though, none of these things are problems, because EVERYONE is biologically immortal. You'll be able to hang out with the same people for centuries, and always have folks who can understand your problems. The ennui of immortality only applies when a centuries long life is the exception, not the rule.
On another note, if you become bored with life after so long, it says more about YOUR unwillingness to get out of your rut and try new things, than it does with life _itself_ being a drag. If you find new things to occupy your time, that problem won't arise. Mass media ALONE would produce more entertainment to occupy me than I could ever watch, and this is likely to remain true even if immortality became a thing tomorrow and I was watching such things every waking moment from now until my death of unnatural causes. It's a massive pool of entertainment resources, and it's constantly being added to. All of this BEFORE I try my hand at making my own.
Let's not even consider, this is a situation in where great artists just. Continue on. There is no death of old age before the completion of their great work, there's liable to be people with literal centuries of experience in the arts!
Honestly? As an amateur artist rn, if immortality actually comes to pass, I see myself... Idk, making my own sort of MCU? My alternate universe of stories in comic format... Or whatever format I'm up for atm
Personally I have no issue with the concept of immortality itself (as in, biological immortality, not the real one of course) I mean, think about it, it it *does* happen then we'll get to be the first generation!
We'll be those who look at AI and get to say "Ah yes, you're marrying one of those? I remember when that technology still was but a distant dream..."
Or stuff like that, plus you'll surely never run out of jobs since, as a first-gen person with more skills and titles than almost anyone else, every company under the sun will try to hire you over the new, less experienced lad who was just born 200 years ago.
Things to look forward to, no doubt
I am not babysitting my grand-uncle! Great grand pappy is just going to have to hire a robot nanny
They prefer to be called artificial life form.
Robot Nannys probably aren't advanced enough to count as 'alive'. They'd be like a slightly smarter siri.
You'd probably not find many AGI wanting to work as a nanny (although I suppose there might be one who is programmed to find being a nanny just as fun and exciting as humans find sex...but it seems like a niche market, especially considering that if they're smart enough to be alive, they're smart enough to realize the horror being created by eldritch beings that are almost beyond time to babysit Cthulhu.)
trans- and post-humanity is gonna get weird FAST...
You'd also have a few generations that were raised almost entirely by these Nannies that would not be very quick to agree with you.
Drew McTygue I have met most of my good friends through school and have met many girls and have many relations because of it. honestly if it wasn't for school, I have no idea what life would be life socially. I think that it wouldn't be as bad as you think it would be
"Robot" will be regarded as a racist term in the future; as Steve rightly noted a more politically correct would probably be "artificial life form". Of course in order for that to happen they will need to pay insurance fees and taxes. After that they may even vote. No taxes, no rights, no vote :)
History class would get interesting.
"FUCK YOU! My grandfather didn't commit war crimes! Doing X was all right back then... Why don't you talk to him about it if you're so sure?"
"Well my great grandfather on my mothers side, and 2 grand children, and my great grand uncle's nephew's former room mate said he did! As all of them!"
"Excuse me professor but I was the president back then and that's not how it happened." "What are you talking about? I WAS president at the time." "I thought you were the Secretary of State?" "No, I was the Secretary of State the century before that."
Imagine meeting Isambard Kingdom Brunel on the street today, that would essentially be what it would be like. "Oh, you did all of that yet I never have heard of you? Thats some neat stuff you did." "Yeah, perhaps thats because you're not from my country so you didn't learn it in school."
Jeremy Leyland "actually teacher that's not what happened, my great great great great grandfather was there, you can even ask him!"
To quote Nwabudike Morgan,
I plan to live forever, of course, but barring that I'd settle for a
couple thousand years. Even five hundred would be pretty nice.

Loved that videogame glad to see other people play it.
Imagine this, instead of retirement it would be coined as a "long vacation"
Loved and miss it. The new attempt doesn’t quite capture it.
yeah i never heard a good argument against immortality, that wasn't completely short sighted or just taking the world of today adding immortality and pointing out how it doesn't work. of course it does not, you adapt the world and it would probably be a much better one.
I find people are often stuck in the mindset of... that's life... that is how the world works... which prevents them from thinking about how it could work better.
Yes. It is like a hunter gatherer tribe saying that aggriculture can't work, since there would be a hell lot of more people and there are not enough caves where they could live in.
Some species are effectively immortal, and they manage to get by.
It's exactly the necessary changes to societies that are the worry.
Zamuroy Exactly and it's that narrowminded, unimaginative, anti progressive, willfully ignorant, way of thinking that annoys me. And I tend to dissociate myself with those types of people.
Plus you can easily see that, given the education and option, most people in general (and women in particular) prefer to have fewer children, later in life. If anything, immortality is the only thing that will stop the paradoxical death spiral of civilization itself.
Zamuroy yea but most people with dead realities wouldn't become immortal unless their kids or grandkids the immortal process then the parent would do it
A personal nightmare for me would be a civilization where you need to spend the first 100 years of your life trapped in school.
Meh, you wouldn't have to though, because learning those basic skills isn't going to take more than it does today. As the author of the video said, you wouldn't have to work or study something you don't like, that would let you make a lot of money, simply because, you'll have all the time in the world for children and family later, and therefore you won't need to be making so much money.
Especially considering that people are going to improve speed and efficiency of learning by a lot. There is already enormous gap between skilled learners (mnemotechniques, mindmaps, stimulation with electricity) and "normal" learners. Imagine what will happen in next decades, once we develop technology to do virtual reality lessons, or perhaps even just download needed knowledge
Nightmare for you. I'm in my 40's and haven't gone a year without taking a class except while overseas in the military. I would love spending centuries at a university learning and teaching.
The key thing about extended lifetimes and post-scarcity civ, if you've got both, is that there is very little that you 'have to do' if you just want a reasonably happy and comfortable existence. As the others said below, you will as fast if not faster than now, but you aren't required to do such things unless you have a goal in mind that requires them.
I can imagine prerequisite knowledge really piling up over the centuries so that 20+ years of experience is required for most jobs and education is based on degrees that take 50 years to complete. Combine that with our current system of compulsory education and you have a recipe for hell on Earth.

This has been one of my favorite videos.Your imagination based in reality and science and the accurate scenarios you discuss are unlike anything I've ever seen on this site. Brilliant, thank you.
Great video as always. One thing that I haven't seen talked about here or elsewhere is the problem of risk aversion. People who can only die in accidents may become so risk averse that they end up living their lives like Howard Hughes (without the weird personal habits) because they are so afraid of some sort of accident that might kill them.
I think because it is so hard to predict, some might take a longer life and grow more risk averse, others less. I am sure the older one gets the lower the odds of dying the next year would grow though, except where will to survive diminished or a sense of invincibility was kindled. Its hard to say.
@Isaac Arthur
If you're around a couple hundred years from now then mind uploading will make this a moot point however. As much as I find the gameplay of Eve Online boring, it has a fascinating backstory, namely that people die constantly, but then they are uploaded into a new body. I think that will become the norm three or four centuries from now (so you will die several times, but your consciousness just goes into a new body). Of course you also have to take into account that scientists living that long may find ways of storing consciousness within DNA itself, at which point you could survive if just one of your cells does.
Johnathan Martin 200 years from now I am sure the human body will not be as fragile as it is now. Be it through bionic means or others, the human body will be resistant to pretty much everything. But ofcourse, that is possible when we firsr extend our lives to live 200 years more.
If we have the technology to live forever, then we have the technology to fix the damage done in accidents - probably
That is very true, you have to take risks and it is probably the case that those who don't take risks will die anyway. You need revivification too.
I actually know about a Russian guy who killed a bear with a pocket knife and another guy who "won" a fist fight with bear. The first guy was protecting some idiot hikers from a bear they pissed off by shoving his down the bear's throt and stabbing the bear in the neck. The second guy had been some kind of boxing champion in Canada and keeping up that athletic life style he was jogging and somehow found himself between a mother bear and her cub. Mama bear didn't like that and attacked the guy. In the shuffle the guy got in a couple punches and the bear cub get back to its mother's side, so the mother bear decided to leave.
Some people are just badasses :)

I haven't bothered to check through the hundreds of answers, just wanted to mention, in case you haven't read it, the Red Mars/Blue Mars/Green Mars trilogy, for the sake of storyline continuity, extreme life extension was employed. People on Mars did end up doing daring, dangerous sports, such as using flying squirrel suits to soar in the thickened atmosphere, in the thermals. No spoilers: One of the leading characters dies accidentally because of such risk-taking behaviour, which is quite upsetting and jarring during a good read. I actually cried.
Isaac, I actually wish I could converse with you, in person, as a real life friend. As a high-functioning Aspie, being shut in is not as traumatic for me as for others, but I miss substantive human conversations. You ALWAYS help me to think ore clearly, and cause me to immediately bring to mind examples of whatever you mention, from the over 400 fiction and non fiction books I've read over my life. Everything you say makes me think, or wonder, or want to ask, "But what about...?" If I ever run for political office, which I have been considering (which is hard, given my mental deficit to gift ratio), I would be honoured to have you as at least an inspiration, and more so, if we were properly acquainted. You remind me of a non-fiction version of one of the best authors of all time, Piers Anthony. Oh, yeah. Btw, Piers **also** wrote a Mars trilogy, but his was using science, fantasy and magick, creating a fuller Tarot deck along the way (which I consider a Psychological tool, rather than a true predictor).
If you **ever** need any consulting help in my areas of study, please ask. I have separate Bachelor's degrees in Psychology and Religious Studies, separate minors in Anthropology and Biology, after an Associate of Arts.
My late dad got me into sci-fi. Mom got me into Sciences. They both were college educated. At 52, living with undetectable HIV for half my life, and artificial hips, I long to become immortal. My life course was taken from me, altered, and in spite of me fighting back, HIV is a genuine pain. To close: My life often sux. You make it suck so much less. Thank you.

On the topic of skills like artistic abilities (IE, playing music) one of the main limits would be what the human body is capable of (unless you augment yourself), the other would be what the listener/viewer is capable of understanding. For example, a transhuman author might write up a book with a plot simply too complicated for unaugmented humans to follow without great difficulty.
Same thing goes for music-a transhuman musician might eventually find normal music too simplistic and start exploring music in ranged beyond the baseline's ability to hear it or understand it. For example, lots of ultrasound notes playing faster than a baseline ear could listen to it.
This would be absolutely fantastic! I could pursue every game, novel, movie and other type of media that has ever came out and will in the future!
I very recently found your channel, and I'm continually astounded at how you can create such thorough, comprehensive, and interesting material on such a regular basis. These are the sorts of videos I would be content to wait a month for.
I for one can't wait for Thursdays now :)

Episode too short. Needs extension...
Honestly this video gives me hope when I get down, thinking about my dead end job and how I'll never get to learn the things I want to learn, or contribute to civilization in any way aside from helping produce overpriced cars.
I come back to this video every once in a while and watch it to remain hopeful about the future.
Have a career for 100 years, then spending the remaining 500 or so years exploring the galaxy. Sounds good to me.
My favourite channel and broadcaster on youtube by a long mile. Big fan! Thank you Isaac!
I rarely comment on any video, so you know that I mean it when I type the following. I love your content! Great stuff. I tend to watch them within a day of release and it is worth it every damn time. Keep it up, you are reaching the critical threshold of subs!(or whatever it's called when sub number rapidly increase) All of a sudden you'll have ten times as many subs, and you'll have earned every last one.
Thanks Alexander, I hope you're right, though to be honest I prefer the 'slow' steady growth, the channel has 40x as many subscribers as this time last year :)

*Frnkn shw, But with a bear? As far as I know, doing so with a wild animal as ones opponent is not too common of a practice.
There's also bear wrestling, alligator wrestling, and pig wrestling.
Ah.. but it is safer to do greco roman wrestling. And was greased pig wrestling not use as a form of entertainment in days of yore. As for alligator wrestling, I did see a man fight to put on a pair of alligator boots. And that looked painful enough.
I laughed myself off during this part, Isaac surely knows how to be funny!
Now I don't know of any statistics about this but anecdotally, from what I heard, lots of researchers will tend to change the topics they work on over time, either as they feel they have contributed enough in their current field or because they want to find something new-and-fun-to-them or sometimes directly out of activism (like, for instance, there are quite a few people who used to resarch, say, fundamental physics, but then transitioned to climate sciences because they consider the topic of critical importance) so with that in mind I'm not entirely sure the people who first successfully find ways to craft arbitrary lifespans will end up researching that same topic for their whole arbitrarily long lives.
Sure, interest vary over time but while you might change focus and get a little rusty on the original, you never really lose that expertise and can scrub the rust off rather quickly, often emerging with greater expertise from having new insights from letting it wait and looking at other things.
I agree, and immortals make the ultimate renaissance men.
That's true enough
I agree. Additionally I believe there are new insights to be gained from studying seemingly disparate fields and sciences. Using the example that Kram gave, perhaps a biochemist or even a sociologist could add a unique perspective on climate science, potentially leading to a breakthrough that may not have happened if someone didn't connect interdisciplinary theory or phenomena.
I could never get bored with life - there's just so much to do and learn!
And Mars would open up in a century opening up A WHOLE NEW PLANET.
Then Venus!
Another awesome episode, Issac! Even if we never live to see life extension technology become a reality, it is important to set goals by prioritizing them. When something is important, you make the time, regardless of how long you live! :)
This is one of your best, Isaac. If we do achieve radical life extension in our lifetimes, I sincerely hope you never get bored with making these videos. I could watch these forever.
I seldom comment but I feel obliged to say how amazing these videos are, you can see real effort and dedication. I had an immense feeling of joy when I realised that this wasnt a new channel and that I had many more videos to watch. Heres to hoping this channel really takes off and gets the attention it deserves.
"Live forever or die trying" - Isaac Arthur
Existence is painful
Unexistence is dreadful
I do not think existence is painful. Then again, I have had a very fortunate life so far. And I wish everyone could have that.
well said Dave
Existence can be painful, and I've had a less than ideal life, but there are wonders to discover, and experiences to be had, and for those I have a will, and a desire to live, although I also accept that eventually I'll die, and I just hope that it's with some dignity- not getting murdered or caught in a car crash or "what have you".
Minus the religious-ness, the way I think is probably a kin to how people like Issac Newton thought (& think).
When I say this, I mean the part where I'm in wonder by the world & discovery.
I was unexistant for all the time in the universe till 30 years ago, and didn't suffer a bit from that. Was very uneventfull though, so i'm not looking forward to unexisting again :)
And again I feel like crying out of happyness after hearing your view on future possibilities... Thank You!!
I've been watching your videos for a while now, and your uploads are slowly becoming the best part of my day. Thanks for the effort you put into your videos. :)
I am excited for the next episode. It is difficult to attempt listing them or contemplating an alient that communicates with sights and sounds (like us) trying to communicate to an alien that communicates mostly with electricity or chemicals just because of the limitations of those mediums.

Nah, there are always new games coming out so you're still fighting an uphill battle unless you want to just select a few to master and ignore the rest
Video games would come out at such a pace that you wouldn't have the time to spell their names.
I look forward to these videos every week and tell all my friends about it. thank you sir and please keep it up.

I'm nearly 18. I really hope I'm young enough for that.
there's probably not much difference in chances between 18 and 0. chances increase substantially at older ages, but once down to 18, most of the negative results comes down to "not coming for centuries."
I was thinking of 18 as opposed to 40.

The point is that that damage could be fully repaired. Maybe you took a few years off your lifespan (I've had my fair share of sweets and 2 hours of sleep before an 8 hour school day), but it'd likely still suffice for all of the damage to be repaired so that you and I could live indefinitely.

The king asked the shepherd boy, "How many seconds are there in eternity?"
And the shepherd boy said, "There is a mountain made of pure diamond. It takes an hour to climb it, and an hour to go around it. Every hundred years, a little bird comes to the mountain sharpen its beak. And when the entire mountain is worn away, the first second of eternity will have passed."

It does nothing to give you a sense of the scale of it and is just one of those self congratulating jerk off session to make someone sound wise and insightful when they have all the depth of a sheet of tracing paper.
@@PhDyMy yeup...I'm a total piece of shit. Fundamentally unlikable...but also 100% right.
I hope to see a lot more progress in the near future in this area!
OMG I looked for this argument for years and finally I found a video talking about what I wanted to "know". I love this channel!
The end of this video is a destroyer of anxiety. What a smart person.
One thing I'd posit to be among the largest cultural shocks is that -- after the first wave of stubborn old folks refusing the pill died off -- you'd come to a point in humanity where *every* person (or almost every person) you ever knew would die a violent death.
Physically, this shouldn't really be considered "bad", as most people who die violently do so with ultimately far less suffering for far less time (many never even knowing, or only knowing for a few seconds, that they're about to die) than those who die naturally.
Emotionally though, this could get weird. Think of every person you will ever know (friends, kids, grandkids, parents) being like those one or two folks you know who died in a car accident or were tragically murdered. No more _"he lived a good life and was ready to go"_; no more _"at least we all got to say goodbye and be by his side"_. Your relationship with everyone in your life - instead of just a few people - would conclude with that shocking phone call.
I'm not discounting that some folks would simply stop taking the pill by choice, but I truly believe they'd be few and far between. I think most people who say _"I wouldn't want to live to be 150"_ are only saying that because our current view of that involves about 80 years of walkers, poor eyesight, back pain, health issues, and being considered "the old guy".
Also interesting: what happens to the cost of prison populations when billions of people are eventually serving "life sentences" simultaneously? Do we just make murder a 100 year crime at that point?
Only rarely. Incidents of death by violence would decrease due to increased risk aversion and better trauma care. Maybe it's true, "everyone you knew would die by violence," but those deaths would be increasingly rare events. Most centuries, everyone you knew wouldn't die at all.
I'm 21 I'm 99% confident I will live to multi-centuries simply because I'm certain I'll live enough to see the technology that will allow me to live long enough to see the perfect technology that allows me to live until accidental death.
unless you go hunting lions with a nerf bat.
Best channel on TH-cam! Most fascinating topics with depth and intelligence unmatched.
This channel is the best. I always feel warm inside after finishing a video.
TheCool Cat he is very optimistic, and its refreshing.
Hmm, interesting episode Isaac but I was kinda looking more forward to the actual technologies involved in life extension. You briefly covered a couple but then quickly jumped to what life would be like with this technology instead. Perhaps you can do another video about the different types of research being conducted into longevity? I rely on you to dumb science down to a level where I can understand stuff! :-)
Try the Sens link, they do a good job
I wonder if human brain can take in all of those knowledge and memories of living a couple of centuries.
Two centuries should be fine, half a millennium might be a different matter for most people.
I think I would be fine, as I have a different perception of time to most people. For example, there was someone I thought I hadn't seen for 3 years and it turned out to be 7. People think I've been with my girlfriend a long time, but to me it just seems fairly normal.
My memories go back a *long way*, I remember a hell of a lot (nothing like that of someone with an eidetic memory of course) and would certainly be fine with a few centuries.
The problem of everyone one is close to dying is (with the exception of my girlfriend) one I've already encountered and can cope with. With a few centuries one can cultivate a variety of friendships including, presumably, with other long lived people.
It's complicated. The human brain is really nothing like a hard-drive (which has a very finite limit on how much information it can store) and the truth is we don't really understand how memories work. Current estimates are that the human brain in it's original and unmodified state could hold more information than the entire internet. Of course actually getting it to hold that information, accessing the information once we have it and making sure that important memories aren't overwritten is the tricky part but I don't think most people would struggle with several centuries or a millennium of memory. In the intervening centuries though we would be developing technology to help the brain work faster, store more memory and be better at accessing all of those memories.
If they can not they just die. problem solved.
We will be fine. Our brains already discard unnecessary memories. I mean do you remember every second of yesterday? No you just remember the highlights and some vague overview of your day like what room you were in at approximately what time but not every small moment you made. And s the amount of time that has passed between now and some moment in the past the less details you remember about it. And this would still be true. But Instead of not remembering if something happened this day or that day or this month or that month it would be this year or that year or this decade or that decade or this century or that century. You will forget you lived in a state or country for a decade or two. But if you see a picture you may remember it and few things that happened during that time but not most things. And the same will be true of skills you learn if you haven't used them in 50 r 200 years you will likely not remember them perfectly and forget a detail here and there about them especially the more complex ones and will need to relearn or at least practice them again.
My worry example exactly, I'm 70 and it gets marginally harder to remember details of what happened in my past each year. Names are particularly hard to call up. It's not senility, I can still bring them up, it just takes longer. What this grows into in a hundred years is a problem for that time. I would still like to live a longer life but see many problems
Every time he said he couldn't or wouldn't get tired of life it was great. Everyone is always so downtrodden, it's depressing. He is already a genius but still wants more.
The part where Isaac said "I've never been bored with life or not wanting to live it" blew my mind.
I can't remember a time in my life where the experience of days didn't feel like drinking a cup of wet cement haha.
The biggest problem we would face would be plagues. Ageing is a biological adaptation that forces you to recombine your genome and produce new variants. Stagnant gene-pool combined with overpopulation increases the risk of an infectious disease specializing for that particular gene-pool. Don't assume medicine will somehow fix this in the future. Bacteria and viruses are currently evolving faster than medicine progresses, despite the fact that medicine/pharmacy is the fastest growing field of study, spending 16% of income into RnD (which is double than any other industry). The antibiotic-resistence-crisis is currently the biggest problem humanity faces (maybe on par with grobal climate change) and potential doomsday scenario.
Even if we develop successful life-extension technology describled here you will be lucky to survive your 200ths due to annual literally decimating plagues.
Make the bacteria immortal as well ;)
While it be folly to assume we'd be plague proof. I think you might be overestimating the problem.
If everyone is healthy then we got good immune systems the number one defense you can get. (except for those few diseases that kill you via your immune system over responding)
And that RnD budget, could be spent far more effectively. An anti aging serum is by its very nature going to cure a decent amount of the diseases we spend the majority of our RnD budget on.
A plague is a disease that can kill an otherwise healthy person and can spread quickly. It is by definition a kind of disease that an anti-ageing serum does not fix. Sure, improved heathcare reduces a risk of disease becoming a plague, because it limits its lethality and spread, rendering would-be-plagues impotent. However, it actually does no good when a real plague eventually occurs, which is an eventuality.
A society that lived centuries/millennia with no plagues occurring may be set up to prevent plagues, but is unlikely to be set up to deal with them once they came. We are talking about a scenario where people are basically immortal and suddenly a real deadly treat appears. That is a recipe for societal collapse if I've ever seen one. A societal collapse is an epidemiologist's worse nightmare.
Most RnD spending is going towards diseases like cancer, and many other conditions, problems that generally happen to older people. If your not spending money on any of those avenue's you have a lot more funding for other research.
Plagues can kill perfectly healthy people, but are less likely to do so. Only known historical exception to that I know of is the great influenza outbreak. Black Death, white plague, and ect, were still capable of killing people with good immune systems but the young survived better then other age groups.
Societal collapse is always possible, but given our history, you need a plague with a fatality rate in excess of 50% to really destroy a society. Anything less then that is generally just a set back for a few generations.
KohuGaly you're failing to see that it's possible to engineer oneself in order to become something else. One would not remain a stagnant organism in the future but evolve through a different mean than reproduction.
Can't believe you didn't mention telomeres, they are a big part in current aging theories.
Of many of them yes, I did mention them of course, I just cut it out. There's usually like four or five scripts for these things and it was in one discussing the pros and cons of Programmed Death theories of aging. There's never enough time for everything in the episodes. I needed to address Wear and Tear as the best known theory, and Free Radical as one of better known modern ones and as a 'simple fix' option, in the end the others weren't vital.
Lobsters are supposed to potentially live indefinitely long, at least if the shell could be repaired.
Ah I understand :) Regarding the complexity of the whole aging topic, I highly doubt that it's going to be solved by a magic pill :/, i think it will be a long and difficult process tackling all the different aspects of aging one by one. I wouldn't think at all that it's possible to reach immortality in our lifetime, if it wasn't for the unpredictability of artificial intelligence development and resulting scientific progress. Great videos though, keep it up!
If telomeres are the silver bullet, then we just have to watch Liz Parrish in about 20-30 years. She is supposed to have managed to lengthen hers.
I like your intros. The presented scenarios always crack me up.
Yeah I'm getting fond of doing those, one of the suggestions I got for improving the channel that was a good idea.
I so look forward to your videos every week. amazing work!
If people had the ability to live for a very long time (5+ centuries or something), would mutations of DNA become much more significant due to our extended lives? Do you think that could become a problem? Or if we had the technology to live that long would we be able to counter the effects?
That's already a growing problem, as life expectancy has been increasing. If disease, hunger, violence or crocodiles don't get you, something like cancer eventually will.
Or, it used to anyway - cancer survival rates are increasing fast.
The same technologies that could extend life could also repair genetic damage. (Might be the exact same process.)
I'll see you all in a thousand years from my palace on the moon.
I love the fact that the closed captions you get 100% even with the speech impediment, goes to show how speaking clearly and properly goes a long way, even if you can't pronounce your 'Rs' perfectly.
Yes, my dirty secret is that I would encourage folks to have the captions on even if I had no impediment. It lets me use a three pronged attack, spoken, written, and visual, to get info into folks' heads :)
impressive, keep it up you legend :)
Always great to see your videos. I liked how you added more of a personal touch with this one. I for one enjoy hearing how your own perspectives and experiences relate to the topics at hand. Hopefully we can all live and contribute to society and each other for many more generations to come.
Yes I always avoided that in earlier episodes for fear of tainting them with my own opinion too much, I've been trying to straddle letting a bit more of my own perspective in without too much bias, but its tricky.
Thanks for your reply. I have decided to become one of your patreon supporters and I for one would like to hear more of your personal insights and opinions. Sometimes those intuitions are really the synthesis of deeper intellectual analysis. Maybe that could be a rich source of content in the future? Wishing you well and looking forward to your next videos. :)

How to live longer until humans can live forever
1. Go to space
2. Go out of are solar system
3. Wait for a few earth decades
4. buy the product if it’s out
5. You can live forever
Why do we need to go to space for that?
@@Kakantor probably to stop aging or something
@@hatemastertenn1048 But why do you need to go to space for that?
I have no idea what I even meant now since this was 1 year ago
I thought that if you were in space you could stop the process of aging
@@hatemastertenn1048 yeah i also make comments i forget about 😂
im happy that i found this channel as i gone thru all and literally all available science shows, because during my work (as IT specialist) i tend to listen to any documentaries or science shows and quite frankly this is better than most of the shows with so called super scientists of our age ...
Discovered this channel about 4 hours ago, its now 3.30am, and i cant stop watching
Welcome on board, I hope you got some sleep though, the channel isn't going anywhere :)
The sociology problems raised by extended life are way more challenging compared to the problem of achieving extended life. :(
Oh yes, a lot of them will probably 'sort themselves out' but are likely to do so the way many of our problems have, by coughing and uncomfortably looking the other way while those folks on the rougher side of things 'got sorted'
If you think about it, we will be the ruling class of this gerontocracy if we survive until this technology becomes available so we have a duty make sure our descendants will have fulfilling lives. I suggest that sports should be split into ages further. With the same for bands, I also believe that people will still listen to new music and bands because the young still decide the latest culture.
But surely after 50 years or less of the radical life extension tech, they would have developed the tech to enhance themselves a lot. At about this point superintellegences upgrade themselves to hyprintelegences and a few years after that you have a matrioska brain full of digital mind(s). Don't assume that people will stay people for hundreds of years, this video shows what happens if radical life extension is discovered but then we stop researching these things.
I'm not assuming that, but you know I prefer to isolate changes and talk about a single tech somewhat in a vacuum, I covered the alternative path in the original Transhumanism episode. Anyway, while I would expect a lot of folks to go that path, many others might stick to baseline bodies. Many folks will hesitate at life extension, but of those who do, many will hesitate at something more radical too.
@@isaacarthurSFIA How long do you think it will be before radical life extension becomes possible? I've heard it could come as early as the 2030s.
Numberjack Fiutro the most reasonable predictions are for about 2040, if at all
Your channel is finally blowing up! Glad to see credit where credit is due. Keep up the good work
This channel is gold, it is like all the topics you are interested in, all in one place, amazing, really nice work.
Thanks John!
Whenever the breakthrough happens (and it will in max 30 years) It will be the most important scientific discovery in history, the equivalent of liftoff for humanity.
yeah what about the creation of mecha jesus 2? able to turn children into wine?
not THE most important one i think. but at least somewhere on the top at the very least.
but we would not have come here without fire, aquaculture, the first steam engine and electricity.
i still consider those slightly higher.
Why liftoff? Seems like it might be the opposite. Longevity implies risk aversion. Humanity might turn inward and stagnate. The decadence of empire writ large.
How can it stagnate if people get to get smarter for hundreds of years.
Right now people actually get smarter (in terms of iq) till 40, After that it's just accumulating experience.
The employment issue will be somewhat trivial, as we transition to a post-scarcity, fully automated society. Longevity is less a threat to unemployment than automation through AI and robotics (regardless of whether we merge with technology or not - even if we don't, we will still automate all jobs).
Ppl are always going to want to compete. Yes we will not be spending our time making houses or fiddeling someones taxes but things like art and sport are the types of jobs ppl enjoy doing and there will be a shortage in these.
We will automate sports and art too.
I'm sure we will but wheres the fun in that? I think you are missiing the point. Just becuse we can does not mean we will. I could go and get all my food placed at my nose if I wanted but I like cooking and I also like to cook for others and others like my cooking. All this could be done for us that does not mean that we would like it that way. Bolt can run very fast but a motabike can travel faster but yet we still watch and enjoy watching a human be the best that humans can be and not all of us will be able to be that good but that does not mean we will not try to be better.
_Just becuse we can does not mean we will._
No, actually we will.
That doesn't mean that people won't be able to do those things, in their own homes or communities, but it will become irrelevant to the economy.
Just like you can play chess with your best bud right now, this means nothing to the international chess tournaments.
You can throw a football with your buddy in your backyard, or play a game of tag football with your kids at the local park, but you're not going to play in the NFL.
Similarly, robotics and AI will take over everything professional. There will be no jobs, menial, intellectual or creative, left for any human to do.
Within reasonable limits (that do not use excessive resources or damage the environment) you will still be able to do all those things on your own, it's just that most of the world won't care.
This is where I think you are missing the point. 'That doesn't mean that people won't be able to do those things, in their own homes or communities, but it will become irrelevant to the economy.' Please tell me how ppl kicking a ball around helps the economy or mankind in genral. It does not, just the same as the the economy would be no worse off if the mona lisa had never been painted.
It is not the fact that thousands of strokes go in to making a painting, it's what the painting means to the person looking at it. You can make a rocket that travels a X mph and that fact can not be contested as to X per £ but a painting or a style of sport are subjective as to how much value ppl place on it. My favortite sports ppl aren't the best at what they do but it's the way they do it that makes me like them.
Just because a computer will be able to do everything twice as good, twice as fast does not mean that the value added by something being done by a human, for the sole reseason of doing it, vanishes.
Yes we will have robot sporting leagues and human leagues and human vs robot leagues.
The point you are making is that if you are not the best at something (that is completely pointless) then you should give up on it and let someone/thing eles do it. That is very sad and ignors human nature. Not only to ppl get a kick out of doing pointless things but other ppl get a kick out of watching other ppl do pointless things. And if the pointless thing happens to be a service I can buy then we have employment.
Regarding retirement and such, I think we would end up with cyclic careers.
Work for 40 or 50 years, "retire" for a few decades and just chill. Then spend a decade refreshing your skills and learning new stuff, repeat ad infinitum.
As for someone spending a few centuries getting overwhelmingly good at something I think those would be the outliers. Most would get bored and move on to something new.
I really can't describe how much i love every video you make
You can get hundreds of years of interest on your savings account. This could concentrate all resources in the hands of the old
Hey man. I really think you should change your channel name. For whatever reason people are clearly drawn to Catchy channel names that you know, associate themselves with a certain subject or whatever by name, i.e. Sci Show, PBS Space Time, Numberphile, etc. So I really think it would increase your popularity to do that. Thanks for considering!(if you did haha)
I nominally have, the channel went from Isaac Arthur - because it was originally just my regular old gmail account to basically being SFIA, I'm holding off on formally changing it till I've decided if that's what I want to go with.
Ah ok. Would you consider a bunch of suggestions that I came up with after thinking about it, by any chance?
:) Where were you three months ago when I was asking for them? Yeah go ahead, I'm not locked to a brand yet.
Sorry haha I think I started watching just two months ago : P. But great though I'll start thinking!
I like the channel name because it sounds very science fictiony and mysterious, like Isaac Asimov (I, Robot) and Sir Arthur Conan Doyle (Sherlock Holmes)
Thanks for another great video. Your content is almost always thought provoking.
I'm fairly new here but I just have to say, Isaac, your videos are fascinating works of art. This is quickly becoming my favorite channel. Thank you for taking your time to share your knowledge.
Thanks Nathan!
We humans tend to be rather abusive to each other and ourselves. 80 years of emotional trauma is hard enough, but 800 years of collective emotional trauma would be impossible to handle. I see no change in humans's desire for abuse no matter how long they live. Life extension technology is likely to advance far faster than humans are capable of evolving emotionally.
Biological aging will be ended within 10-15 years, regardless of where we're at today. Once we apply deep learning and even better AI systems to the problem, then it's a simple matter of how long it takes deep learning to collect the data and then solve the problem, which won't be long at all.
What people tend to discount is the idea that humans don't have to discover immortality at all, we just need to invent the AI that will do it for us.
eh, maybe, but ai isn't magic, you can't just say it'll solve all the problems.
It will discover all the solutions. It will be up to us to implement those solutions.
it will discover nothing unless it's general ai. until then, computers will only be as good as the scientists.
That is also incorrect.
Narrow AI have already been utilized in making novel discoveries. I could provide links if you want.
khuh...so you're not just a brainless enthusiast? yes please give me a link!
This really lifted my spirits, thanks Isaac!!
Ooooh. Been WAITING for this one.

I think the rolling stones are giving it a good try
one of my concerns would be a monopoly on the drug. Granted the knowledge on how to produce it might be there, but politicians big business have a way of taking things and controlling them. Something should need to be done to prevent monopolizing. Secondly there is already a generation gap between The Young and the old. This could divide people and cause problems. I do think that eventually society would even itself out. Another thing is we've already had life extension. Many years ago the life expectancy of a human being was around 50 years so as time went on a group. I believe now it is considered the life expectancy of a person in America would be around 80 something. I'm using speech to text so if there's any spelling Oddities do forgive me.
Yeah that's why I skipped that, with the open release, its obviously a concern but its not really a life extension concern, just a general monopoly concern like with an OS, water, power, phones, etc. Big issue but not specifically a life extension issue.
Space Oddities??
+Charles Smith "The spice must flow!" Good call.
+Isaac Arthur Suddenly, the power struggles of the "DUNE" universe look almost plausible. Solutions/complications would be totally speculative, so I get not devoting undue time to it; that's what SF is for!
