An artist who rips off other great works are still developing their talent and skills. They can then go on to use to make original works. The machine will never produce anything original. It is only capable of mixing together things it has seen in its training set.

There is a very real danger that of ai eviscerating the ability for artists to make a living, making it where very few people will have the financial ability to practice their craft day in and day out, resulting in a dearth of good original art.
