> he very fact that he has to go around saying 'AI is inevitable, suck it up you live in our world now', proves that it's not true.

If somebody visits a flat earther conference and says "you all need to accept the fact that the earth is not flat!" ... then this certainly doesn't prove that the earth is flat. I think you trip over your choice of words. If s/b in general has to go around saying that then your reasoning makes some sense. But if s/b in particular (like Schmidt) has to go around saying sth then this only proves that this particular person has some personal intention or feeling s/he wants to express. I couldn't care less why someone like Schmidt feels like that but I have my ideas. Maybe he just identifies with AI financially and ideologically and likes to provoke.

It's not literally him as an individual saying it this once, it's the large amount of it in total.

There's people who go around bothering flat earthers, but despite flat earthers claiming the contrary, they're quite small in number. No mass media effort, no corporate propaganda, no CEOs mentioning all the time.

The largest it ever got were things like the netflix shows. These are pretty illustrative; All of the big attention is not so much on "these people must be convinced of the roundedness of the planet" and more on the dissection of why these people refuse to accept something that is quite easy to prove across a wide variety of otherwise unconnected experiments.
