The only problem with code is that you get caught. I lived a secret life with ink, and paper. You use pixels, and patterns described by numbers. It is fascinating, the endless associations of algorithms, the paisleys of probability. But then the patterns don’t fit and—well, you realize that elegance and simplicity, quantifiable complexity, are aesthetic concerns, that quantity itself is a quality of imagination. It seems like life. But it’s really just managing multiple threads.
