Except that the opinion of people like Stephen Hawking, Bill Gates and Elon Musk is definitely worth more than any "majority" thinking differently.
Nosense. That's just hero worship mentality. Very much like listening to Barbara Streisand quack about her favorite obsessions.
Bill Gates' opinion is worth more than the average person's when it comes to running Microsoft. Elon Musk's opinion is worth more than the average person's when building Teslas and the like. Neither one of them (nor anyone else, for that matter) has anything but the known behavior of the only high intelligence we've ever met to go on (that's us, of course.) So it's purest guesswork, completely blind specuation. It definitely isn't a careful, measured evaluation. Because there's nothing to evaluate!
And while I'm not inclined to draw a conclusion from this, it is interesting that we've had quite a few very high intelligences in our society over time. None of them have posed an "existential crisis" for the the planet, the the human race, or my cats. Smart people tend ot have better things to do than annoy others... also, they can anticipate consequences. Will this apply to "very smart machines"? Your guess (might be) as good as mine. It's almost certainly better than Musk's or Gates', since we know they were clueless enough to speak out definitively on a subject they don't (can't) know anything about. Hawking likewise, didn't mean to leave him out.
Within the context of our recorded history, it's not the really smart ones that usually cause us trouble. It's the moderately intelligent fucktards who gravitate to power. [stares off in the general direction of Washington] (I know, I've giving some of them more credit than they deserve.)
