Ah, but you see, Julia is both too popular and not popular enough! It's too popular with the wrong people (bad unserious people) and not popular enough with the right people (good serious people).

Not particularly my opinion, just an observation - when I've brought it up with physicist friends, they only knew the language as something Quants play with. Then again, physicists are weird - they seem to reach for C++ more often than Fortran.

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.

we're actively trying to move more end-users of high energy physics (HEP) into Julia https://github.com/JuliaHEP/
