I'm sure I've still got a bunch of MP3 files from Napster on a hard drive somewhere, but yeah, that genie was put back in the bottle. This one can too.
The analogue here is AI art week be legitimized, and the artists who profit will be the ones who let their work be used as input for a cut of the profits. And nobody will be able to compete with them, and the owners of the machine will be able to set the profit rate as they choose.
... That does sound like a new stable equilibrium, actually.
