If you follow the news, you've probably heard something about 5G. It's been billed as the foundation of a new technology revolution, as the next thing that is going to change the way people do everything. I'm always cautious of people trying to make predictions like that, since it's notoriously challenging, and we have a tendency to only remember the people who were right about what happened in the past, but even if half of what is being hyped about 5G comes to be, it would change a lot...on the backend. Users might not even notice much of a different in daily life. Yet for all that this is supposedly a world-changing technology, it seems that most people have no idea what it actually means.
