So any attempt to tame a technology that is that embedded in our society is going to be difficult.
Hackers have demonstrated they will break any code possible, just because it's there. So there will undoubtedly be many attempts "spoof" not only drones, but also any system that depends on GPS to know where it is.
Humphrey's students have shown that it can be done, although their first attempt focused on a relatively stationary drone. Next, they will try the same trick on a moving drone, which will be considerably more difficult, unless it is moving in a straight course. If it's making evasive movements, it will be harder.
Let's see if they succeed. As Humphrey noted, we all could use a wakeup call.
