Agree. Being enough for these people isn't enough, they also think we should care what they have to say.
I would not include simonw with the other 3 at all. His opinions are informed by use instead of just other thoughts. Simon also releases a lot of utility tools.
These are sales speeches. They are over hyping it. AI has its niche but they are trying to plug it everywhere.
Maybe they have a point. Maybe hooking people up on software tools so they are incompetent without will pay off.
Hinton talks are hilarious. He goes from explaining perceptrons to huge claims like "this is what understanding is", "that's how our brain works", "linguists are cranks if they don't agree", and "this proves there is no god" but the last one as some weird little anecdote involving some religious migrant worker, and implies heavily that disagreeing with him is equivalent with having religious beliefs.
Geoffrey Hinton seems to be in the headlines constantly going "godfather of AI" and giving some random obtuse warning or call for action.
Eric Schmidt also spends a lot of time yapping.
And of course people like Gary Marcus.
Simon Willison also does a lot of writing but at least his blog is actually useful information of actual tests and news.
