A very typical in tech circles, but completely misguided thought. While I might not be able to plumb a whole house, rebuild an engine, or blow my own glass there is immense value in being able to diagnose and solve basic problems with things that you interact with every day. Things like replacing a sink, installing a toilet, changing oil/tires, and even replacing a window pane not only can save you time and money. Both in the do-it-yourself sense, and in knowing enough about the problem to not get taken by someone offering a solution. Isn't this the same kind of attitude we criticize many managers, executives, and normal people for having? Making decisions about anything without being educated enough to do it?
