This week I paid a visit to the University of Guelph, from which I graduated over twenty years ago. They’re fine people and it’s a fine school, and I’ll have more to say about that, but I learned some some shocking numbers. First, of Guelph’s 18,000-or-so students, around 70% are female. At the Veterinary College, it’s around 90%. And in this year’s graduating class of 50 Computer Science students, 4 are female. The visual effect is not subtle: everywhere you look there are swarms of bright, healthy, eager-looking young women. And in the CS building, the usual geekboys. Guelph’s population, they tell me, is not untypical for modern universities. What does this mean, a couple of decades from now?
