With the proliferation of AI content creation tools as the catalyst, we're going to go from a natural decentralization cycle to a natural centralization cycle which will be bringing trust back to sources like WSJ and NBC nightly news. Obviously you still have to keep your guard up but that was never and will never be not true.
Further, many of the social media sources today will work to show "real" sources versus AI generated content, etc. and that will result in some of those sources themselves just becoming centralized authorities on what is generated and what is not, though that job is more difficult.
