I am always surprised that people are surprised about Fortran's activity! It works and your code will likely still compile 10-20 years from now. (It is certainly not perfect and sometimes it is annoying, but the same can be said about most programming languages).

In short: the authors make a good summary of these ideas:

- Entropy in thermodynamic equilibrium is well understood. The early theory (before statistical mechanics was developed) fits well with our modern understanding.

- The analogies made about entropy are not always good and indeed, if you try to match the physics with "entropy is disorder" it does not always work.

- In non-equilibrium situations it is, as the author points out, more complex.

Regarding the last item, even Stephen Hawking postulated some strange ideas about the universe having to rewind past some point in time, so that the big crush would be the mirror of the big bang.

This short video explains the system very well. https://twitter.com/DGlaucomflecken/status/14846797598292090...

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.
