Well, what Papert and I did was say 'Well yes, it’s going to get pretty big and then we’re going to have to make administrative theories of, how do other levels of the mind manage all those resources so they don’t go crazy and one of them doesn’t dominate the others and how is all this stuff regulated?' Well I kept working on that and then at some point in the early 1970s, Papert began to think well, we’ve got to verify these theories and see if they work, and so instead of working together all the time now, we were being more separate. And he started groups of training people to work with children and see how... how their learning actually worked and trying to give them new kinds of tools... especially the first... this was the period when computers became cheap enough that, for the first time, children could be given access to them and Papert pioneered that area and discovered that fifth graders could... were incredibly productive and original and in a few hours many of them became very good at building complicated programs and making machines do really interesting things.
