In the early PDP-11 days, Unix programs had the following design parameters: Rule 1. It didn t have to be good, or even correct, but: Rule 2. It had to be small. Thus the toolkit approach, and so forth. Of course, over time, computer hardware has become progressively more powerful: processors speed up, address spaces move from 16 to 32 bits, memory gets cheaper, and so forth. So Rule 2 has been relaxed.
