AI by no means necessitates de-anonymization, though I have no doubt that that will be the narrative that politicians and corporations will run with as an unquestionable truth. All you need is something that implements a mix of a reputation system and a web of trust and you're good to go. Technically pseudonymous, not anonymous, but it would give you basically all of the benefits of tying online activity to real identities without any of the downsides. It would also be completely decentralized, which would prevent large players from manipulating the political landscape on a mass level.
