You get to keep it, but if the software itself depends on a foundation made of sand, you can still be out of luck - especially for desktop applications that tend to rely on all sorts of libraries that just can't keep themselves from breaking their APIs and ABIs every few years (and those libraries have their own dependencies, etc). Of course if time is of no essence you can spend it keeping the software up to date, but being able to waste that time doesn't really excuse the underlying foundations forcing application developers to waste their time.
