The premise of the article is stupid, though...yes, they aren't us.

A human might grow corn, or decide it should be grown. But the AI doesn't need corn, it won't grown corn, and it doesn't need any of the other things.

This is why, they are not useful to us.

Put it in science fiction terms. You can create a monster, and it can have super powers, _but that does not make it useful to us_. The extremely hungry monster will eat everything it sees, but it won't make anyone's life better.
