Very interesting social experiment using AI.
The site is a little harder to get details out of than the PC Magazine article was, so in essence, picture taking human babies and raising them in the environment of your choosing. That's what this project is all about.

The people who put this together figure they can test all sorts of situations when the AI peeps become smart enough.
