The interesting bit about this post is that with that resume, you can still feed a family in 2022 (okay, you won't need any assembler, and one from the set { Fortran, COBOL } will do). I wonder if Python and JavaScript will get you that far 50 years from now?
JavaScript is 26 years old, Python is 31. They both continue to grow in importance year-on-year, JavaScript because there is nothing on the horizon which will plausibly replace it, and Python because a large number of industries and programmers genuinely love it.
I think there's a nontrivial chance they'll both still be languages of primary importance in 50 years, but I'd bet my bottom dollar that they'll at least remain as relics yet needing support the way Fortran and COBOL exist today.
