Doesn’t seem plausible that both c and c++ are more popular than python.
This is the impression I get from a few proprietary software vendors I used to work with, and those that pop up at local events in my area. I can't name one actively migrating to C/C++, C# is big if your stuck on Windows.
That being said, I have been diligently avoiding proprietary software for the last few years. My life is much happier without it, ain't got no licensing worries :D
