(like it's sort of no difference than paying someone to voice something and share it)
I think the stuff that is completely generated with no human in the loop is a different category for me because it can be used for things at scale like, bots on social media, or ads in a podcast generated just for you, etc. As long as there is still a human in the loop making the editing decisions, it feels not categorically different from the world we have today.
AI/Human combos can still be valuable. More broadly I'd argue that that's how almost all tech works. E.g. there are still textile workers, just many less of them producing much more clothing.
Like, there's been computer-singing voices for awhile, but they always sounded pretty robotic and goofy (e.g. Microsoft Sam), and I think for a long time people just assumed that to get mostly-realistic voices, you need an actual singer. Yes, it still requires a bit of human tweaking to make it perfect, but I suspect that if put to the test it would reduce the cost of making a song substantially.
