Now this one is scary. The X-47B. X is always military signification of experimental, the B tells me this is the SECOND revision of this tech.
The aircraft is completely autonomous. No human involvement other than a likely command channel for permission to fire, etc.
In other news I hear the U.S. is going to permit drone flights in the United States. So do look up, smile, mouth the word “FUCK YOU” and make an appropriate rude gesture when one flies overhead. Paint anti-corporate messages on your roofs. Do your part to oppose the expansion of Skynet.
