if your not hip on what nanotechnology and bio nanotechnology is you should get hip
human cell is the size of about 10 square micrometers which means that hundreds of today's smallest transistors could fit inside a single cell. (bio nanotechnology)

goes beyond that - bumble hive project- blue brain project- apollo project- they are creating a real life matrix - which they can control your thoughts - see threw your eyes and take control over your actions threw an artificial mirror
like world with avatars of every human on the planet with quantum computers . threw self replicating bio nanotechnology that wires you up just like a reciever.....guess what comes next - true 5g
