Sure but remember most static languages are 20+ times faster than Ruby so even with compile times you might still come out way ahead.

Ah, but a lot of bugfixes are developed by making small changes to understand better what is going on internally during the bug symptom, and there the compile time is more important than the compile/test time.

True, and languages that are slow to compile like C++ really suffer here. But Java and Go compile so quickly it's hardly an issue.
