when i think of anyone, i can think of aspects of their personality that i dislike (for example, me not capitalising words or i?). but do you wish he'd retired because of his personality? or because you didnt think his contributions were worthwhile? or over-hyped?
btw i recently asked gpt this exact same question posed by op!, was quite the diplomatic response i got.
because of the things he's saying about where AI goes in the future, that the brain works like an LLM, and in particular his doomer-ism about LLMs.
he was wrong about many DL paradigms and didn't contribute in any way to the advances that brought us LLMs for at least the last decade, but now since he won the Nobel (undeservedly imo) his wrong opinions get publicity and misinform the public and decision makers.
i think it's the mark of an intellectual to recognize when the world has moved on so far that your idea of it is outdated and wrong. he missed that mark.
If he gave up on ideas because other people moved on, he would never have done the work that won the prize. It took someone very stubborn to continue working on neural nets back then.
