So pardon my cynical twist, but what are you doing with that 20,000×20,000 double-precision floating point matrix you say you need to invert today? If you answer "nutt'n, I jus kinda wondered what it'd be like, you know", you should be very happy that I am most likely more than 3000 miles away from you, or I would come over and slap you hard.

The theory is the result of listening to the problem. When the theory acquires a life of its own because some people like it more than the real world, all kinds of uninspiring, uninteresting things happen, so the key is both to listen to the problem and to study the theory. But always remember that just as much theory is bunk as there are buggy solutions. There is nothing more wrong with "theory" than "solutions" – both their quality and their applicability are orthogonal to their existence.

Just as other information should be available to those who want to learn and understand, program source code is the only means for programmers to learn the art from their predecessors. It would be unthinkable for playwrights not to allow other playwrights to read their plays, but only be present at theater performances where they would be barred even from taking notes. Likewise, any good author is well read, as every child who learns to write will read hundreds of times more than it writes. Programmers, however, are expected to invent the alphabet and learn to write long novels all on their own. Programming cannot grow and learn unless the next generation of programmers have access to the knowledge and information gathered by other programmers before them.
