I think the landscape will be our current one but wildly exaggerated once convincing video fakes are cheaply available.
Even with AI spotting/detecting fakes, conspiracy minded folks will just dismiss those AI detections as tech/government/media suppressing the truth. Similarly, actual events can be dismissed as AI edited for the same reasons.
While this sort of exists for text already, people rarely fact check memes/ideas and video is a hell of a lot more convincing.
