My uncle worked at the National Institutes of Health for about 35 years doing bioinformatics and protein structure modeling. In FORTRAN. Always in FORTRAN. He knew other stuff, but the bulk of his work was always FORTRAN.
I didn't learn fortran in university, but I did have to learn it for a job. It's still THE language for scientific computing. So in any job in or adjacent to scientific computing, you're bound to run into fortran.
