You're right of course, but look at this like someone who's not a nerd. You don't have to maintain your own car. You don't have to cook your own meals. You don't have to fix your own plumbing or electricity. If you get sold a lemon, or were fed spoiled food, or your apartment is unlivable, then it's not really your fault and you often have legal recourse.

But you do have to learn a lot about the computer, and if you do it wrong everybody just calls you stupid. I'm lucky it's not like that for dancing.
