It really gets going at 8 minutes in -that's when he starts describing the experiment.
His conclusion: that, given access to a computer monitor, touch pad and the internet, groups of uneducated children with zero adult intervention were on "a learning curve almost exactly the same as you would find in a school" (that quote is from around 15 mins into the talk).
