In my experience there is a substantial subset of programmers/computer scientists who don't even consider any dynamically typed language as worth their time. In their view, these are at most for beginners or small projects. This bias is like a huge blind spot...
No, actually, proponents of Python or R don't generally claim that all statically typed languages are useless in practice. In fact I don't remember any evidence of that.
Also there doesn't seem to be any evidence that dynamic typing is detrimental to programming.
And I don't see all non-computer-science-scientist-programmers learning Haskell any time soon.
