If you have a social circle where 100% of your contacts turn to an LLM first, not only have you buried yourself deep in a niche filter bubble, but you have also surrounded yourself with some of the planet's most misinformed people. If I were you, I'd be worried.
I don't think there's a measurable difference between his social circle and those who still rely on traditional media (news, TV, mainstream "journalism") to form their view of the world. It's just another cage.
