I used to think that but I can't recall the last time the compiler saved me when augmenting or refactoring someone else's code - the IDE beats it to the punch every time - and static typing is not substitute for a good test suite. On the flip side, i use interfaces and dependency injection constantly in java to work around static typing. In python, i write probably ~20% the amount of code because i never use interfaces, wiring logic or convert types.
