you're reminding me of this 30 minute talk from 2014 "the birth and death of javascript", in which he supposes a future where CPUs basically run webassembly directly https://www.destroyallsoftware.com/talks/the-birth-and-death...

Reminds me of Jazelle[1], which allowed some ARM CPUs to run Java bytecode directly. AFAIK it never really caught on.

It also probably didn't help that Jazelle was locked behind an NDA.
not exactly, the idea is to have a normal cpu like arm or x86 but the kernel doesn't ever deal with native binaries, only web assembly, and the performance penalty of running stuff in a VM gets offset by disabling memory protection and its performance penalty, since memory protection is already guaranteed by the VM.
