>I used to think this had to correlate with dominant programming language – c/c++/go vs ruby/java etc. but I don't know if that fully explains it.

There most definitely is a correlation here. Language shapes Thought and the more complex/expressive a language is the more does that Programmer have opportunities to explore new paradigms/ideas that expand his mind. Your knowledge footprint increases and you do get better than somebody else who learns a "simpler" language and/or just stays at the surface level without any exploration (i.e. i will just use this API and not learn about anything else).
