I missed your original post so I don't know your full argument about random computer programs. At the risk of being way off base I'll let you in on some interesting research in that area. It's called Genetic Programming. It's a method of creating computer programs to solve problems which the programmer doesn't know how to solve. It works just like evolution. A large number of random computer programs are produced and become the "initial population". This population consist of several hundred to several thousand individuals (not millions). Each program is then "run" and ranked according the it's ability to solve the problem. The worst 65% or so are destroyed. The best are sexually combined to produce computer programs which contain the traits of their parents. Some are given random mutations. The new population (parents and kids and mutants) are "run" and their relative ability to solve the problem evaluated. The best are kept and mated. The worst are destroyed. This process is repeated many times with 10 to 100 generations being typical. Eventually a program emerges which is quite good at solving the problem. THIS ACTUALLY WORKS!!!! A program is evolved which will back up a tractor-trailer rig to a loading dock! All programs are written (or evolved) in common Lisp. For more info see Genetic Programming by John R.
