"Science is what we understand well enough to explain to a computer. Art is everything else we do. ... Science advances whenever an Art becomes a Science. And the state of the Art advances too because people always leap into new territory once they have understood more about the old."
-- Donald Knuth
"A computer is like a violin. You can imagine a novice trying first a phonograph and then a violin. The latter, he says, sounds terrible. That is the argument we have heard from our humanists and most of our computer scientists. Computer programs are good, they say, for particular purposes, but they aren't flexible. Neither is a violin, or a typewriter, until you learn how to use it."
Marvin Minsky, "Why Programming Is a Good Medium for Expressing Poorly-Understood and Sloppily-Formulated Ideas"
