30+ second compile times is definitely not something inherent to statically typed languages. 200ms is rare, but plenty of static languages manage <5s for large projects and much less for small ones. Not to mention that a good IDE will incrementally check types in well under a second as you type, so the need for frequent test runs is lower. That said, I agree 100% about the importance of fast feedback loops.
