Fortran is with us in a technical sense, but its use is tiny. I’ve done about six Fortran to python rewrite projects during my academic career. No-one has seriously suggested going the other way.

I will bet you any amount of money you like Python will be more popular than Fortran in 5,10,20 and 30 years.

You are defintely not risk averse. Try to look back 30 years and see how much popularity has changed since then.
