Hello, TCS assistant professor here: he is legitimately respected among his peers.
Of course, because I am a selfish person, I'd say I appreciate most his work on convex body chasing (see "Competitively chasing convex bodies" on the Wikipedia link), because it follows up on some of my work.
Objectively, you should check his conference submission record, it will be a huge number of A*/A CORE rank conferences, which means the best possible in TCS. Or the prizes section on Wikipedia.
I don't deny that his output is highly valued among AI researchers.
Provocative as my question may be, the point I wanted to make is that his most highly cited paper that I already mentioned is suspiciously very in line with the OpenAI narrative. I doubt if any of his GPT research is really independent. With great salary comes great responsibility.
