Luis von Ahn’s presentation about human computation

This is Luis von Ahn giving a Google TechTalk presentation about “human computation”.

He talks about Capatchas and the ESP game among other things. He’s particularly qualified to talk about them because he basically invented them.

Really interesting stuff. It’s been online for about year so this isn’t a very timely post, but it’s so worth watching if you haven’t seen it already. Enjoy!
