Comment 50 years ahead (Score 2) 246
I heard a myth a few decades ago, that top-secret work in most fields is at least 50 years ahead of the current published state of the art. I can't begin to imagine what that would look like here.
What would that look like here? What sorts of things do you think are solidly plausible within the next 50 years of work in the field of nano-technology, and how would we detect them "in the field" today, if we were to look for them? How and where might we start to look for them, if we wanted to be likely to find something?
I know there were published discussions about silicon based listening and transmitting devices, bugs, that were smaller than grains of salt. I also know that there was great published fervor over single-pixel cameras, and, impo, I have seen a surprising gap in entangled non-return imaging. I expect "they" have working, single-photon, non-return-imaging cameras on grains of silicon too small for the eye to work with, so perhaps nano drone swarms used for data gathering/surveillance, where each drone is less than 0.1mm across?
When I look at robo-cat, and the alleged robo-squirrels or robo-insects, I think they have such swarms that can be ingested/injected/otherwise-implanted inside animals that don't realize they have become "listening posts". What would you do with a fully-functional jet-engine that was only a few microns across? I remember sub-cellular size bar-codes made by shooting proton based cylindrical holes in silicon, then lithographing layers of gold or other stuff to make the code, then removing the silicon substrate. Could we put markers into people to inform future medical reconstruction such as "non-invasive" 3d printing of organs in-vivo? How would we detect sub-cell-size tagging, or fabrication? I like the idea of nanotech-driven bio-energy harvesting. Why can't we turn trees into solar panels by hacking into their organic photosynthesis?
