AI has been creating news articles for a long time. Especially for the business journals out there. Now it creates college essays. But it still makes basic errors. Like a college student might, I guess. And it creates new images too.
Here's what it can't do: it can't direct itself. The user gives it a goal. It doesn't have goals. Marty's right that it could theoretically rest for a million years. But it won't wake itself up. It will wake up based on a predetermined plan or an outside stimulus, and then it will do things it was programmed to do.
Just like newjagscity said robots don't have emotions or creativity, the root problem in both cases is no will.
