Ladies and gentlemen, I give you the Distributed Flight Array, a group of robots programmed to seek each other out, link up, and then take to the skies all without any human interaction. I don’t know if I see “Skynet” emblazoned on the side, but it wouldn’t surprise me if it was there in really fine print:
These little buggers are quite ingenious. They use accelerometers and tilt sensors like you’ve got in your run-of-the-mill smartphone to keep themselves level and linked up, communicate through IR, and stick together with the use of magnets. Right now they’re simply programmed to reach a certain altitude, shut off and tumble to the ground and then reassemble in a random pattern, but I’m sure it will only be a matter of time before they’re weaponized and given enough autonomy to decide that humanity is a threat and needs to be wiped out.
