What about the era of flash cartoons? Remember "End of Ze World"? In a way that's throwaway crap. Or it could have been written as a comic strip, or animated manually. But Flash kinda opened up this whole new world of games and animation. AI is doing the same.

One that comes to mind is a sort of podcast-style of two cats having a conversation, and in each "episode" there's some punchline where they end up laughing about some cat stereotype. Definitely low quality garbage, but I guess what I mean by "barrier of entry" (sorry for the buzzword), is just that this is going to enable a new generation of content, memes, whatever you want to call it.
