Language bias becaiuse internets
The issue I would have with this survey is that it is biased towards languages that are common for internet software development and therefore posted up on Gthub etc. If you took a look at much commercial software you might find a good level of use of older languages such as C, COBOL, PL/SQL, and even old 4GLs like UNIFACE and Pro-IV. In scientific computing you will find FORTRAN still in use.
