That analogy is misleading, because you don't have to run a marathon to get a high school diploma.

I'm not advocating that students use this to cheat on their homework. I'm just pointing out that most people reading an algebra textbook aren't in there for self-improvement. They just want a good grade.

I think the impressiveness of what these guys made is the best argument for what a mistake that is. The effective 0% unemployment rate of engineers in SV shows what you get when you're not willing to be "bad at math." I know you're not advocating for that attitude, it just drives me nuts.
