Say what you will about RMS, but he really did change the world of software.
Most code (except for very specialized applications) just isn't worth much
anymore (because of competition from open source) - which is part of why all
these old code packages are now freely available.


Although I suppose the development of portabilty - which really took off with
C and Unix, although it had existed to some degree before that, q.v. the tools
collection in FORTRAN we just mentioned - was also a factor, it made it
possible to amortize code writing over a number of different types of
machines.

There were in theory portable languages beforehand (e.g. PL/1), but I think it
probably over-specified things - e.g. it would be impossible to port Multics
to another architecture without almost completely re-writing it from scratch,
the code is shot through with "fixed bin(18)"'s every other line...
