I've been designing a microkernel for 7 years now and to hear many of the ideas I've had over the years put so succinctly is so satisfying. Clear, direct, amazing talk. Thank you SO MUCH for posting this.
The x86 and ARM both have 4 “rings” of privilege. For some reason, every OS out there only implements ring 0 and ring 3. Still, it should be possible to write an OS that uses all 4, or at least 3 rings
OMG that old dude is still around!! Garnot Heiser is an old man long past his prime and long past his time. He should have been put out to pasture all long time ago.

This is awesome, thank you for posting it on TH-cam.
I have a question would it be possible to have more than just User and Kernel space?

Ah those sweet pre-SPECTRE times full of hopes.

Yes, I agree Heiser and his research group should definitely put away their laptops and take up knitting.
gee, why so much hate? Be constructive.
Heiser is busted! I found a darknet site with sel4 exploits and they all work on the version of seL4 that apple used.......
teclis High Elf does Apple use sel4?
