Controlling a robot with your thoughts

Saw this on CrunchGear. I think AI is completely kewl and completely scary all at the same time. I mean, if you can control a robot with your thoughts, then that just seems like one logical step away from the reverse being true, doesn't it? If the signals can go in one direction, ultimately they will be able to go in the other at some point?

Not to go all tin-foilhat on this, but... If you think about it, we can't control nature; we can't control animals; hell, we can't really control our PCs (viruses and SPAM, anyone?). So what makes us think we can control artificial intelligence over the long run? If we've learned anything from sci-fi movies, it's that at some point the computer will become smart enough to rebel. I'd like to think that we're smarter than that, that we'll just reach over and switch off the power button, but some days I'm not so sure.

And then you add some weird human-robot hybrid into the mix and, well, let's just say that I might not be sleeping as soundly tonight as I thought I would...

What do you think? Is AI good for us? Creepy? Do you think there's potential for evil lurking in those electric tendons and silicon cells?
