"If you buy a hammer that doesn’t hammer your nails, then you go back to the hardware store and get another one, no? And that sort of makes sense, except that it also cripples you. You end up with the rote permutations on the low-lying fruit of algorithms. You treat programming like you treat Excel. Instead of invention, discovery, and experimentation, you get expressions, behaviors, and pre-defined routines that you can mix and match, but never alter. So, is that wrong? I’m not sure. I teach people to think of code as tools because it gets them started thinking that code is interesting. They can do things with it. They are, without a doubt, horrible programmers, and they will continue to be horrible programmers hamstrung by their tools, for perhaps years, or in all likelihood, forever. They implement things they barely understand, leverage things they don’t appreciate, and run into mistakes that they can’t comprehend. And, I think, that’s probably ok. It’s not a failure of mental capability on their part or failure to communicate on the part of their professors: it’s simply not necessary for being a designer working with interaction."
