You’re a programmer for a big corporation that makes, oh, I don’t know, aluminum cans, and there’s nothing quite available off the shelf which does the exact kind of aluminum can processing that they need, so they have these in-house programmers, or they hire companies like Accenture and IBM to send them overpriced programmers, to write this software. And there are two reasons this is so frightening: one, because it’s not a very fulfilling career if you’re a programmer, for a list of reasons which I’ll enumerate in a moment, but two, it’s frightening because this is what probably 80% of programming jobs are like, and if you’re not very, very careful when you graduate, you might find yourself working on in-house software, by accident, and let me tell you, it can drain the life out of you.... It costs so much money to hire these programmers—typically a company like Accenture or IBM would charge $300 an hour for the services of some recent Yale PoliSci grad who took a 6 week course in dot net programming, and who is earning $47,000 a year and hoping that it’ll provide enough experience to get into business school—anyway, it costs so much to hire these programmers that you’re not going to allowed to build things with Ruby on Rails no matter how cool Ruby is and no matter how spiffy the Ajax is going to be.
