Even with a reliable system, you notice how real-world conditions are never perfect. Occasionally, a glare or slightly worn label can cause a hiccup, and you have to remember that no system is 100% foolproof. It’s a reminder that while technology like this is impressive, human oversight and occasional adjustments are still part of the process to make sure everything runs smoothly.
