Mindshare and buy-in might be an issue of the ecosystem though. Not enough lisp/Haskell devs.

Maybe thats because while those languages solve particular problem, they, or their proponents aren't solving the particular problems at hand.

Perhaps, but that's speculation. If nor corp will invest outside fortran, cobol, C++ or java then there's a limit to how much problem solving a small community can do on its own dime.

The point is, I think speculative characterisations of <community>-dev members as lazy/unproductive is off mark.
