Fortran is hot at the moment :-) See "Resurrecting Fortran" (blog post by Ondřej Čertík https://news.ycombinator.com/item?id=26445438 https://ondrejcertik.com/blog/2021/03/resurrecting-fortran/ ) about the promising Fortran "standard lib" and the Fortran community in general (see the related website https://fortran-lang.org/ ). The story here is interesting but lacks a bit about this wider context.
