On the radio recently some guy said he didn’t want his new kid to have electronic toys, so he looked up his old favorite, Legos, on the web. He was horrified to see websites for obsessive adult male hobbyists, who devoted decades and huge sums to develop lego masterpieces. He worried his kid might grow up like that.

Me, I worry my kids will grow up to be the opposite: sophisticated. While such folks can be very smart and capable, they are uninteresting.
