The physical and the cyber combine to make a new threat
Reporters don't usually write the headlines for the stories they prepare. The editor of this story, Drone Use on the Rise, Public Safety at Risk, might have been asleep at the switch. The public safety aspect is the threat to cybersecurity that is called out in the article. There is brief mention of weaponizing drones, but that is not a possibility, it has been demonstrated in the past, just not put into practice — for whatever reason I don't understand.
The reality is that drones will be used for a mixture of good or bad. Don't let the forecast of ill use deter you from the positive uses for your programs.
