Apart from Python, RE the SO survey, I always wonder to what extent the percentage of that survey is actually meaningful, because it does not give any information about the correlation with actual users. As for me, I’ve never participated in that survey, and I wonder how many Fortran users actually voted in the survey (even for active SO users).
PS. Not trying to “critisize” the OP’s post at all, but just my impression of the SO survey overall…
