At this point we could probably get more original movie content from AI as the movie studios just remake old movies...

Honestly though I think it could co exist with traditional forms of content creation at least for a long period of time as I don't see in the immediate future it having it's own original style like a human. That being said, even though my above comment was mainly a joke, it's not like a large portion of content isn't already basically stolen from someone ealier.
