Black mirror did an episode where they discussed bees that were drones for the purpose of pollination, they were also used to spy on people and to assassinate people. They were connected to AI, a supercomputer and facial recognition software. They could break through windows and fit through cracks. I think they killed by going in through the ear or nose or some other opening and burrowing in.I didn't want to start an new thread just to post this and I haven't read this entire thread (it's realllllly long) but I thought this link could go here. They are doing ALL kinds of nano tech stuff now.....I thought this example was along those lines, but touted as "look at the amazing stuff humans can create/come up with! aren't we so awesome??!!"
