Can they, though? How many of them actually changed, and how many simply went into hiding?
One of the biggest issues that led us to this point was the tolerance of the racist uncle, the antisemitic grandfather just because "he's from a different time" or whatever. Many of these people never changed, we just started accepting it when it was couched in the right social rules.
It's well known that Trump grew up around former Nazis and active white supremacists. His family's culture growing up was steeped in it.
One of the things about cults is that followers fall into a sunk cost fallacy that means that the longer they've been a member and the deeper in they are, the harder they are to get out until there's a line beyond which it becomes basically impossible. Because to admit they were wrong is to admit that their beliefs were wrong, that their actions weren't justified, and that they're not the good person that they think they are.
The one thing that I disagree with is that most people don't care about AI being shoved into everything. Studies are consistently showing that the vast majority of people don't use/hate AI being shoved into everything. 80% of phones users in one study, 90% on another study for DuckDuckGo IIRC, etc.
