I have an idea similar to yours: in the far future, software will be ancient, largely bug free, and not be changed much over the centuries. Information management software will evolve to a high degree of utility and then remain static because why change bug free software that works perfectly. Operating systems may be easily themed, but there will be no need to change the core that works and has finally become bug free over centuries of infrequent bug fixes. Think of Asimov's "Spacers" society.

What we think of programming will evolve into using incredible high level scripting languages and frameworks. Programs will be very short.
