AI have "tragedy of the commons" written all over it. Here's a number of things that can and will happen medium to long term:

- people gradually stopping to study art, because it will become impossible to find jobs
- AI regurgitating the same stuff over and over, because of a lack of new material produced by actual human artists to train the AIs from (they're regurgitating engines and incapable of true creation because they don't have any actual "understanding" of human culture). Expect a great stagnation in the themes and art styles of games (and other things) in the medium to long term as everyone turns to AI to crank up "new" concepts that will constantly recycle the same crap.
- Oh and another fun thing, AIs will become increasingly trained on crap that was produced by other AIs, resulting in gradual degradation of the results as they will reproduce and amplify the mistakes made by the previous AIs.

And yet people will rush to use it for easy short term gains like "getting more armors in the final fantasy 14 video game" or "not having to pay employees that have ludicrous demands like not working 24/7 or eating".
