Or, you know, being 12 years older and realizing he hasn't turned into a stodgy old man who refuses to use anything but Fortran.

Not relevant to the original discussion or your point, but I've heard Fortran is still in use and pretty performant (and readable) for what it's being used.

Yes, between legacy software (powering expensive and irreplaceable legacy hardware), and a userbase that doesn't care so much about learning the fancy newer tools as long as they can do their experiments, I think it's still standard in many parts of physics.
