Late last year, we wrote about how Australia was paying a stupendous amount of money to try using drones and artificial intelligence to detect sharks off of popular beaches. We were skeptical, mostly because it's hard to make a convincing argument that shark attacks are actually that big of a problem, in Australia or anywhere else, compared to other, bigger problems that we might want to address first. One of those bigger problems, in Australia and in many other places, is drowning--in Australia in 2016, about 120 people drowned on the Australian coast, 60 times more people than were fatally attacked by sharks. Fortunately, the drones doing the shark spotting also happen to carry life preserver pods along with them, and last week, a drone being used for training managed to save a pair of struggling swimmers 700 meters off the coast of New South Wales. According to the Sydney Morning Herald, lifeguards were using the drone during a training session when "a call came through of two distressed swimmers."
