Another book to check out is Vernor Vinge's "A Deepness on the Sky," which depicts our smart dust future in a way I still think about all the time, decades after reading the book. His "Qeng Ho Localizers" - are invisibly small (1mm square and thin) - can be released like a gas into the atmosphere - are powered by low-power, low range microwave bursts - mesh network with each other - have omnidirectional video, other sensors In the book, historians survey the wrecks of myriad advanced societies in our local galaxy area. The find that smart dust, as final-form state surveillance, is a kind of an end game of technological development. That is, it inevitably emerges, and inevitably destroys society. On the brighter side, if you can power/harness the localizers around you, you can expand your sensorium to sense everything they do, which sounds cool.
