Currently it’s an opt-in tool, and I don’t think it is likely OpenAI or Spotify blatantly steal voices. The fact that the tech exists enables that though, a podcast is a perfect training tool for it. But you can’t really uncreate it.

It’s also the sort of thing that unions have been fighting. It improves the technology and makes it an easier sell for any studios or producers to use it elsewhere, like to replace the need to pay a celebrity to come in and record radio station call outs, and long term this specifically takes away jobs from people who translate and dub audio.

IMO it’s good it’s opt-in but ultimately anti-human.
