In order to keep adding cores, AV1 accelerators, SIMD/AI instructions and what not after Moore's law is dead (as it has been for Intel lately), it is either this or adding chiplets. Hint: The latter option is fine if you don't care about power.
- As we get to absurdly many cores, it makes less and less sense for all of them to be fully performant, because software threads just aren't equally loaded. Hyperthreads were the solution to this, but I think won't make sense anymore once you have plenty of small cores, which makes sense to have, both for efficiency and because they give that much more bang for the buck.
