Software that lasts is software that is a joy to use.

Imho the tech, how good you are at programming is all not very relavant when the user doesn't like to use your software.

I have written a small CMS for a company which was replaced twice but every time they ditched it to return to my old simple version.

This is just one example but I think that should be in people's minds when they create software that lasts: people must enjoy using it.

This can even apply to a command line program.
