I really, really, really don't understand what it is that you're saying here. Slow compile times make better programmers? And you base that on one anecdote? And somehow your example coworker would transform into a sensible programmer if you add a Sleep(30000) in the compiler? According to you, it is better if the compiler always makes everyone wait for long periods of time than letting the programmer decide when to pause and think? What??? Are you serious?

When I build C++ stuff at home I go to great lengths to shave milliseconds off my compile time, because it is just so much better to have your program built in under 2 s than in 2 minutes.
