Strong static typing is useful in the environment where the code is not adequately tested. That's because tests adequate to make the code bulletproof will also detect the problems strong static typing could detect, rendering SST superfluous.
So, how often is poorly tested code out there? From the popularity of strong static typing, it must be ubiquitous.
