LeCun at least knows a lot about AI. Most of the Q* stuff is coming from people who know almost nothing.
I ended up unfollowing him as the curmudgeony approach combined with some of the far out stuff was just a bit too much for me. Doesn't really improve discourse in the field.
I could not imagine the same amount of searches and guesswork had they called it "P*" instead.
It seems like Q inherently has some mystery to it. Maybe in that is the least commonly used letter and it rarely is used separately from "Qu"
