But for every tech company with its head in the clouds, there are problems to bring them back down to earth. “There are big technical challenges,” says Ryan Calo, a law professor at the University of Washington. “There’s a bunch of PhD theses that need to be completed before you can build a drone to autonomously police an area, find intruders, and use facial recognition to know who is meant to be there. Plus, having these things stay aloft beyond a few minutes is non-trivial.”"
