It's also not about sticking to what I already know for me. I don't currently know FORTRAN but wish to learn FORTRAN.
There are more factors to language use than design pattern fads. Like efficiency for example, which almost any modern garbage collected or managed language cannot meet beyond a certain level. And that usually gets worse the more "powerful abstractions" one adds. I want to learn FORTRAN because I have been told it has real benefits in terms of ergonomics for efficient code, ie normal looking FORTRAN code is faster than normal looking C/C++/Rust.
Efficiency is a real, concrete and measurable quantity. It is not subject to the fad of the day.
