We've seen this before
Massively parallel CPUs and new languages have failed repeatedly (Transputer, Cell, Itanium, Mill, GreenArrays, Connection Machine), and the pitch sounds like 1980s ideas presented as new.
LLMs change the porting economics
Some argue AI-assisted code translation and compiler work could remove the software-ecosystem moat that killed earlier exotic architectures.
Software, not silicon, is the hard part
Skeptics note compilers, ecosystems and memory bandwidth are the real barriers, and question who would want an exotic chip on an old node with a custom language.
