Hey sure I use sure too much! I like the word OK
Yes you are right nanotechnology is work in progress but its still a recognized science. We have a nanotechnology lab where I work and those guys in that lab would not like to be described as anything but scientist.
Do I have any evidence of implants or nanotechnology working in our environment....video.google.com... yes and I do believe the subject in this video is very real.
You say OUR R&D isnt advanced enough to implant nano bots into us, but thats not to say alien R&D isnt though is it.
