The presenter missed the point about switches (32:22). Polymorphism in that context is advised mainly to benefit from dependency inversion and comply with SRP and OCP.
The problem with checked exceptions is that they have to be handled immediately (which is not always practical) OR propagated with "throws" clause, that requires changing methods all the way up to the exception handler and cuts through all layers (that introduces breaking changes, makes modules/libraries harder to evolve, requires re-testing of all affected code parts, etc.). So the community is moving away from checked exceptions towards runtime exceptions that doesnt' have the aforementioned drawbacks.- Eduards from DevTernity
Good points, horrible presentation. The presenter's use of sound and visual effects reminds me of the over-enthusiasm towards powerpoint transition animations in the early 2000s.
Thanks a lot Victor. As always, impressive talk! Love the way you use sound and visual effects in your presentation!!
Anna Boyko, its you?

Thank you for the great talk! Is there anywhere I can find your elaborated opinion on checked exceptions?

Two Decades Latert -> " Two Decades Later"
For me navigating throw objects is pain. Presentation is too emotional.
