Fortran >:D

  For low-level, fair. I only know of people in astronomy academia who actually use it nowadays though.

    Signal processing stuff is still sometimes written in it.

    There are good technical reasons to use Fortran even in 2022. For example, it avoids** is aliasing (pointers / references / etc.). This allows for some kinds of optimizations impossible in most other languages. It's used in a bunch of small niches, but it has users beyond just astronomy. ** A million disclaimers apply.

      I am aware that hypothetically fortran code is the fastest possible. That said, I am not sure how great this aliasing difference is in practice. There is a reason why most BLAS implementations have been rewritten into C.
