One insight I read about Fortran is that the amount of people using it hasn’t really increased *or* decreased much *because* it’s used primarily in specialized fields that require high performance computing such as complicated physics calculations. The amount of people needing the kind of precision and speed available from Fortran haven’t increased – it’s just that the number of programmers for *other* languages have increased over the decades.
For me, I was pleased that after a short tutorial I realized that I already know how to read it and if I had to work in it it wouldn’t be difficult. BASIC / Pascal / procedural is what I grew up on, so the stye makes more sense to me than object oriented. [which is great for games because games are object oriented, but not so good for calculations which are iterative]
