Oh… good. Hitachi has made RFID chips so small they're calling them "powder," as they measure 0.05mm x 0.05mm. That's a bunch of them up there on the right next to a human hair.
I can't wait until I can have tiny tracking devices stitched into my clothes and sprinkled in my food and everything we do can be tracked by all sorts of creepy, shiftless entities! Whee future, wheeeee!
