Laws always come after culture. We'll have to wait and see what laws countries come up with. There are ill minded people that use power tools like this for profit of their own.

In the meantime, artists need to figure out what AI can't do and use it to their advantage. (Incorporate small changes in requests, have five fingers, etc.)

Would people really pursue arts though? Most people I think would give it a shot and get bored/ give up in a few days. I really doubt patience would be a value people respect or have in a fully automated world.
