   That is true, and not a new story. Regarding the relevance, checkout F18 (Fortran 2018 standard). It's an awesome language for numerical computing: built-in parallelism, a high-level expression like Python/MATLAB, low-level speed

   I have a Fortran codebase which takes about a week to finish a simulation on 10 cores. Rewriting this code in Python and running would take about 50 years to finish the same simulation in serial mode, and at best 5 years if run in parallel

   There are people who want it. Those who know the value of each language.

   As a computational scientist who knows C, Fortran, IDL, MATLAB, Mathematica, Pascal, Python, and R for about two decades, I can tell you that the unique advantage of (modern) Fortran (2008/2018) over any other languages mentioned here

   That is not completely true. It is completely free of charge for academics (students/teachers) and open-source developers. That already covers a significant population of programmers in my opinion. Disclaimer: I am not affiliated with

   interesting, I am a physicist and I use (modern 2018 standard) Fortran on a daily basis, the reason being that it perfectly suits my research needs, in particular, for its concise vectorized array-based syntax. For example, to compute the s

   Nothing is wrong with (modern) Fortran (2018), although I'd argue that everything is wrong with using FORTRAN (77) for numerical computing in the new millennium. On the contrary, modern Fortran (2003,2008,2018,202X) is still truly the

    In my opinion, as a computational researcher, Python was not really meant to be a Scientific Computing Programming environment. It was a big historical mistake to go in that direction. In the near future, hopefully, it will be replaced, by

    Fortran is not worse. Far better than what you think is, really. Just try Fortran 2018 standard and you will see.

    Anything that can access C, can also access Fortran via iso_fortran_env module in Fortran (>2003).

    by the way, three-decades has gone since FORTRAN became Fortran.

    Of course, you can (re)write code in any Turing-complete language in any other Turing-complete language.

    I second that. The book by Metcalf is the holy bible of Fortran.

    The truth is, any language other than Fortran/C is slow for any serious high-performance-computing task (which is not the same as everyday back-of-envelop calculations and plotting).

    Whatever that can access C can also access Fortran these days. Look at the 3 newest Fortran standards, over the past two decades.

    There is really no performance difference between carefully-written Fortran and C codes for scientific research purposes. Really none. But in terms of learning and coding, Fortran is far easier to learn with a learning curve comparable to P

    I highly doubt if there would be any performance difference between carefully written Fortran, Ada, C, C++ codes. The much more relevant question is which one has the least development time for the given task.

    Wouldn't it depend on how those benchmarks were written?

    In modern history, I still use (modern) Fortran (as well as MATLAB, Python, and R). It does what I need to do, efficiently with minimal coding.
