Are you smarter than a four-year old?

RPI researchers have apparently created an avatar in Second Life driven by an AI equivalent to a four-year old human child. Sounds pretty interesting, and could be a good reason to check out Second Life, although I imagine it would be difficult to locate this particular character in the "game."

Currently, the team is grappling with computational tractability issues to do with the sorting of growing amounts of knowledge that is collected as a artificially intelligent character matures.

Massive parallelism perhaps?

A possible future application of this technology could be cost-effective solutions for pesky child-labor laws for TV game shows...
