    Something that was true in 2003 can be not true in 2026 with absolutely no contradiction. It’s a problem I’ve had multiple times with people getting bristly assuming that a push to replace a broken but “working” subsystem with something new and better necessitates a confession of guilt by the people who wrote the original system.

    As problem domains scale up by orders of magnitude, as they have since Linus ranted on 2003, the correct solution changes. Sometimes several times. It was the right solution, but it might not be the right solution now, and both are correct.
