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.
What exactly is this enabling, other than the mass generation of low quality, throwaway crap that exists solely to fatten up Altman's wallet some more?
