I expect what would most-likely happen (could still happen?) is that you'd get differing groups radicalizing different groups of youths via their AI, ending up with hyper-radicalized subsets of society, each filled with their own personalized data and companionship that actively conflicts with each other (and reality).

And arguably, this is already present -- Facebook, Youtube, Twitter, Fox News and the like have done an incredible job of presenting variously alternate and customized timelines to people, radicalizing them with completely incompatible worldviews to many others.

Plus ca change...
