Same same. I don't expect any of my product code to survive for very long.

I suspect some of my open source contributions will live a long time. Not my personal projects that I make open source just in case, but the (very small) contributions to fix things in the dark shadows of established projects with longevity. Some of that will become obsolete and hopefully be removed, and some might get refactored eventually, but if the project is older than my career it's may well last beyond me.
