I know. I meant to say "have a higher seniority in the graph." I assume the sample size was big enough to handle shy Pythonistas and/or overly-confident Ruby devs. :P

I said "I would have expected [...]".

My personal experience is that somebody who doesn't know C/C++ and some UNIX basics is going to write worse code on average. (Settle down.) My personal experience probably isn't representative of anything (I'm a graphics programmer), but I think it shows in the web dev world as well. Puma for example (a Ruby web server I know virtually nothing about) is crazy fast because the guy who wrote it knows about fork and signals. Another example is Bluebird (JS promises lib), which only became popular because the guy who wrote it knows how compilers work.
