I've been wondering if there's a chance the inevitable explosion of hyper-realistic disinformation and manipulation content - of course brought on by genai significantly reducing the cost and barrier to entry to very high-volume realistic multimedia content production - could make the public digital information landscape so obviously polluted and cacophonous that even the most oblivious of media consumers will begin to have their trust of information from purely online sources (or at least social media) continuously erode, basically solving the problem of online disinformation efforts by destroying the confidence in the medium altogether.
Disinformation and manipulation is already such an incredibly invasive problem across all media and all sides of political spectrum that I can’t imagine the majority of people ever changing in the way you describe.
