Your comment reminds me of a pretty jarring experience moving from embedded systems into mobile (iOS) apps. I asked the lead how we know the software is “done” and can ship. He looked at me like I had horns growing out of my head. “We are never done. We just keep developing and releasing until they tell us to work on something else.” This idea that your program can be done and you release the final version is turning into a relic from a lost age.

It’s also sad from the user’s point of view: as updates get more automatic, you have to take deliberate action to stay on an old, working, familiar version. If you’re not careful, you can reboot and your software looks and behaves entirely different. And in the web world it’s impossible! You don’t even have a choice. You are running whatever version the developer decrees you should be running.
