Theory

The moment AI can create written "movies" either by writing, directing, or acting - the AI movie becomes irrelevant and boring because it will feel immediately cliched. The best argument for AI is that human made films are already cliched. Hardly an endorsement.  

Recently, I started playing Risk a bit on the iPad. Playing against the hardest level AI is quite easy to defeat already. I suspect they don't make the AI too good otherwise people wouldn't play at all. But you know who is good? Actual other players...the games are much more challenging playing against real folks. The downside to "real" games is they take too long whereas the AI games are fast. But after awhile the AI game becomes pointless.
