I hope life doesn't imitate art and people get scared to go back into the water because nobody knew that all these mainly harmless sharks were always around swimmers and surfers. With a bit of luck they won't cause hysteria and only report when larger or dangerous sharks are about. Pretty cool though, and I'd feel safer if all beaches with sharks had drones flying over all the time. We don't get killer sharks here, we get basking sharks that are much longer than great whites but harmless, still doesn't help when you come across one while swimming or snorkeling because they can reach 20ft no problem
