"Programming is hard, period. Knuth has noted that its so difficult for him that when he is programming he can't teach courses, and he's among the best programmers in history." This reminds me of something I've read about writing: "A writer is someone for whom writing is more difficult than it is for other people." -- Thomas Mann I wonder if this also applies to programming. That is, perhaps the reason programming for Knuth is so hard is that he has such high standards and that he's working on such difficult problems.
