May I introduce a counterexample? I worked for 21 years as a computational physicist for the DoD. I never saw or heard about anyone using a C++ program. Everything was in Fortran, except for a special-purpose C dialect that we used for programming the Connection Machine. I understand that C++ is used in analysis of high energy physics experiments, though (although I’ve also heard that it‘s being phased out).

I know of some large-scale physics simulations that are using Julia, and it’s widely considered the language to use for new projects. It’s what I use now for my physics hobby projects. I’d never heard about its finance-bro associations. And if I had, why would I give a crap?
