Have you seen the movie WALL-E? The people on the space-ship they're consuming engaging content all day long, nobody is creating anything anymore, so all this must been created by the AI. I'm just trying to say that it's not a novel idea. Writers and artists have been imagining this future for ourselves for a long time.

When you think about it, that's pretty much the history of boy bands, going all the way back to the Monkees. The faces were carefully chosen for demographic reasons, the songs were written by the labels and targeted for specific demographics, the faces' histories were largely constructed fictions (and published through "unauthorized" fan magazines and books that were ghostwritten by the labels and laundered through other publishing companies). The only real difference is that now software is being used for it rather than marketing teams.
