>Their code will never be used by anyone. Critical FORTRAN libraries are still the center of certain types of analysis, and they're often used by _everyone_ in the field. The reason for that stems from two issues: 1. Making accurate simulation libraries for things like weather formation, magnetic field formation or hydraulic fracturing requires crazy in depth knowledge of the systems you are modelling, and takes years of implementing and hypothesis testing to ensure they are accurate enough for academic use. 2. Academics are not software developers, they don't get paid for the software they write, they get paid for papers. They get no reward for rewriting those crazy indepth libraries every decade in the new language de-jour. This is a perfect example of why the python2 to python3 hard-cutoff transition was a terrible idea. "Just update your software" is something you can say to professional software developers with a straight face. You can't say it to academics, or mechatronics engineers, or real estate agents, or photographers, or _anyone else_ who has a job that benefits from a little bit of software but is mostly about delivering something other than software. Well, you can, but they're going to ignore you.
