Which also means they wouldn't be able to do anything about you saying "Hitler was a poopy head".

I disagree with that. There are still people out there doing that out of passion, that hasn't changed (it's just harder to find). Bad actors who are only out there for the money will continue trying to get the money. Blogs might not be relevant anymore, but social media influencing is still going to be a thing. SEO will continue to exist, but now it's targeted to influence AIs instead of the position in Google search results. AIs will need to become (more) profitable, which means they will include advertising at some point. Instead of companies paying Google to place their products in the search or influencers through affiliate links, they will just pay AI companies to place their products in AI results or influencers to create fake reviews trying to influence the AI bots. A SEO slop article is at least easy to detect, recommendations from AIs are much harder to verify.

Also it's going to hit journalism. Not everyone can just blog because they are passionate about something. Any content produced by professionals is either going to be paywalled even more or they need to find different sources of income threatening journalistic integrity. And that gives even more ways to bad actors with money to publish news in their interest for free and gaining more influence on the public debate.
