Is it worth learning C++ for work?

Question

C++ / C#

I want to get a second purely mathematical tower, I myself am not made of rubber. The programming itself is interesting, but not very, ie. I don’t want to grow up to be the boss of programmers or be an eternal programmer. I want the work to be more about mathematical models, calculations than programming. Are there areas in which retraining can actually, and not theoretically, fall without completing the ShADs and others? I understand that all this is much longer than becoming a web programmer, 3-4 years. Or was it necessary to go to graduate school and then R&D departments or IT companies, the train left? Now I'm bad at math.
If we discard mathematics, then how will it be if you learn C ++ for system programming, writing scientific programs? Is there a difference in working conditions (open-space or office system, the presence or absence of Agile, young hipsters or ordinary men) in system programming and web in JS, Java?

Answer 1

For scientific and near-scientific things, python is traditionally used. C++ is a bit redundant for this, IMHO.
