This is mainly because even AI can't make you "not create content", in fact it would help you. So if you are a content creator, and build a brand, don't have to be even just you or your name, could be anything, then you can do it anyway you want at any place.
As long as you have a ton of followers, you can do it at twitter, and want to switch? go to instagram and many would follow, want to switch? Now do at tiktok and many will follow, you want to start streaming? many would follow. So having a ton of people who love your content, would mean you will never starve, no matter how much technology changes, no matter how much the world changes, as long as there are people out there willing to follow you then you should be making some money.
