I don't think audio, image or video generation should exist. I haven't seen enough positive applications to justify the amount of harm these tools are being used to cause.
To give a good use case (audio generation specifically), the 2002 game Morrowind has had a resurgence lately and it's a really great game, but it lacks fully voiced lines for dialogue. A community project called Voices of Vvardenfell uses ElevenAI to generate voice lines from the voiced lines that do exist in the game. They don't take away jobs from artists because it was a monumental (unpaid) undertaking from community volunteers to do this before (there was such a big project but it was abandoned last I saw).
So as with any emerging technologies, I think it just needs to be properly regulated.
