I’m reasonably certain that Schmidt anticipated that reaction after the first speaker was booed. It had the vibe of “These people need to hear the Truth”.
Schmidt anticipated the response, but does not understand it.
He falls flat on his face here precisely because "needing to hear the truth" is a self-contradiction. The 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. Nothing that is actually inevitable is declared as such. Nobody goes to say "The sun will rise tomorrow!"
And this failure is pretty serious. The kids (and wider public) instinctively understand this dynamic even if Schmidt doesn't.
No matter how it's phrased, the only thing these kids will hear is "We are ruining your life", "We are taking everything from you".
It's all but inevitable than worryingly soon, some of them will go "Nothing to lose? Bet." and we will see far worse violence than the failed property damage against Sam Altman's house.
