> I can’t wait for the current systems to become 30 years old. Making changes to micro services architectures written in different languages over multiple servers will be a lot of fun.

This will be bad even if they are all written in the same language, if they were not also all written in the same time frame.

With ancient FORTRAN systems, generally you need to learn the version of FORTRAN it was written in (FORTRAN 77, Fortran 90, etc) and enough about the problem domain to understand what they were trying to do.

With the kind of systems we are making now the hapless maintainer will not only have have to learn the specific ancient language version and the problem domain, but also whatever now forgotten framework was in fashion at the time the thing was written.
