- Worry Meter: 100%
When drones were first used, they were employed by the military. They were perfect to use, as they allowed the military to survey the scene before they went in, and they could be armed to handle some of the combat to keep our boys safe. But eventually, they hit the consumer market. They were a huge hit but caused a lot of issues (such as spying on people), causing the Federal Aviation Administration to make specific rules. Everyone now has to have a license for them.
You can only fly so high and can only be a specific distance from your drone. Obviously, there is no flying in restricted territories nor anywhere aircraft is present (such as airports). Plus, you cannot fly them too close to residential areas. In spite of these rules, people can easily break them to spy on others. What makes them some of the scariest technology known is that they can still be equipped with weapons. While most consumer drones are not capable of this, you can build onto existing drones to accomplish this.
