I only found AI alone can do only crappy graphics, or if they are good, they are too standardized (as happens in most art, human or AI).
With the games, it can do elements. Graphics, music pieces, and some chunks of code.
It programs quite bad. If you are a programmer, you can notice it. Non-conventional or too original games are impossible.
And all this is a very happy news. You can use AI, and still it needs a lot of work from you, as an human, to design and give it sense. It won't take jobs, but make you able, to create what you couldn't do before as a solo or small team.
