If you have profound knowledge of the cloud of problems around programming, of the higher level problems you’re trying to solve, you’ll do a better job programming. This is obvious, and explains why the best programs are always the ones programmers write for themselves, eg. emacs, Google, VisicIlc, etc. And it conversely explains why so many programs are so uninspired, too: if you’ll never use the feature you’re writing, you’re not going to imbue it with brilliance, because the brilliance will never occur to you.
