I have never considered trying to apply Claude/Gemini/etc. to Fortran or COBOL. That would be interesting.

I was just giving my history :) but yes I am sure this could actually get us out of the COBOL lock-in which requires 70 years old programmers to continue working.

The last article I could find on this is from 2020 though: https://www.cnbc.com/2020/04/06/new-jersey-seeks-cobol-progr...
