We said. It would be nanotechnology. Trillions could be within a cc volume.i used to wirk for company that produced micro chips... more specifically they made the machines that actually etched micro chips onto the platers for companies like micro soft to divide and use. now this is back in the the windows 3.5 era. with a company called semi-tool and semi-therm. back then they were printing chips that you needed a high powered micro scope to see. so while i agree with a lot of what you said, I think you are hugely unaware of just how small this stuff is nowa days. Just look at gaming for an example.. computations are currently able of generating in real time billions of pixels to produce real life like video and gaming experience. using this example.. it wasnt but 10 yrs ago we were thrilled at the xbox 1 and its games. the point being that as things have gotten 100x more powerful computing wise, the hardware doing so is infanitly smaller. you literally have miniature super computers in your video cards now.. just like your ever shrinking phone. its quite possible that nano bots are real.. and its not only plausable, but probable that these could run off your own bodies current or electric charge if u will. Darpa says they have the tech.
I think we can all agree that there is an immense amount of technology out there that the general population isn’t privy to?
