I don't think you understand what "type errors" means if you are making that assertion; or your multi-contributor codebase has such excellent test coverage that your tests are doing for you what a modern type system can do for you.

In a dynamically-typed codebase, it's near impossible to have rare type-error occurrence because you're off-loading the type system into into the programmers head (which is subject to human fallibility - even when countered with excellent unit testing!)
