No one ever learned how to update the clock on their VCR. We used those things for maybe two decades and I never saw one with a properly programmed clock. Instead of learning the clock interface, we invented a new system of watching movies and then created the internet so we could have our DVD players update online. No human interaction necessary. It just goes to show you, if something's complicated, just wait a few decades and someone will invent something else that makes it easier.
