I doubt software at the source level will go out of date for a long time.
I expect "extensions" as new hardware (faster CPUs, color, 3D) is introduced.

Binaries will probably rapidly become incompatible as the OS evolves and the
hardware changes.  Most commerical PC software is shipped as binaries.
NeXT doen't have a large commerical applciation base, so this is not a problem
yet.  Binary incompatibility is a major obstacle for PCs such as IBM or Apple
to switch CPU tracks.  Commerical application software must be upgraded then.
