Yes. He mentions that in passing that saying people will accuse him of hating on it because he didn't profit from it. I think his point of view is that his company's attempt was smaller scale and not part of the $10B+ waste?

In any case I don't fully understand what he's trying to say other than negating the hype (which i generally agree with), but not offering any alternative thoughts of his own other than- we have bad tools and programming language. (why? how are they bad? what needs to change for them to be good?)

Well, he’s currently running a startup aimed at making better tooling for the space. So, he’s putting his time where mouth is.

Before he deleted his Twitter account, he claimed AI was already being better than humans and that singularity was only a few years away.

He's confidently wrong a lot. (Even if I happen to agree with his new, more sober take on AI coding here.)
