[Sturgeon's Law---This applies as well to computer science as to science fiction] Sure, 90% of all software is crap. That's because 90% of everything is crap.

Less than 10% of the code has to do with the ostensible purpose of the system; the rest deals with input-output, data validation, data structure maintenance, and other housekeeping.
