Teaching broad concents seems better than fluency in any individual techology (that will be complete outdated before the kid reaches adulthood). I'm not even sure how that would work: Here kid, here are all of the technologies that we think are important to you (and whose companies have supplied us with training materials). You shall learn an iPhone, the internet through Bing, a Honda car, and how to use Facebook. We won't teach you how any of these work, or even any of the basic concepts behind the world you live in, you can figure it out yourself by using Bing.
