Other advantages to generating content: (1) fewer copyright issues. (2) No creators to pay, just GPU bills scaling with the use of the platform. (3) a much smaller critical mass.

Given these advantages I expect the current "social media" to be replaced with a new one, rather than them pivoting. The next big thing after tiktok might be something that only has generated content, where a last final bit of "social" is taken out of "social media".
