David May and his various PhD students over the years have retried this pitch repeatedly. And Graphcore had a related architecture. Unfortunately, while it’s great in theory, in practice the performance overall is miles off existing systems running existing code. There is no commercially feasible way that we’ve yet found to build a software ecosystem where all-new code has to be written just for this special theoretically-better processor. As a result, the business proposal dies before it even gets off the ground.

(I was one of David’s students; and I’ve founded/run a processor design startup raised £4m in 2023 and went bust last year based on a different idea with a much stronger software story.)

Yes David is the man and afaict has made a decent fist of Xmos (from afar). My current wild-assed hope for this to come to some kind of fruition would be on NVidia realising this opportunity (threat?), making a set of CUDA libraries and the CUDA boys going to town with Occam-like abstractions at the system level and just their regular AI workloads as the application. No doubt he has tried to pitch this to Jensen and Keller.
