The truth is, for those of us with lower IQ, it doesn't matter how critically we think, we lack the knowledge and mental dexterity to reliably arrive at a nuanced and deep understanding of the world.
You have to stop dreaming of a world where everyone can sort everything out for themselves, and instead build a world where people can reliably trust expert opinion. It's about having a high-trust society. That requires people in privileged positions to not abuse their advantage in a short term way, at the cost of alienating, and losing the trust of the unwashed masses.
Because that's what has happened, the experts have been exploited as a social cudgel, by the psychopathic and malignant managerial class, in such an obvious and blunt way, that even those of us who are self-aware of our limitations, figure we're as likely to get it right ourselves, as to get honest and correct information from our social institutions.
There is zero chance of making everyone smart enough to navigate the world adroitly. But there is a slightly better than zero chance we could organize our society to earn their trust.
The exact quote is: "I foresee the day where AI become so good at making a deep fake that the people who believed fake news as true will no longer think their fake news is true because they'll think their fake news was faked by AI."
