There&#x27;s also the classic of Eric Drexler, who coined the very term &quot;nanotechnology&quot;, &quot;Engines of Creation&quot;. I highly recommend the read. It&#x27;s very good at extrapolating possibilities and issues, though I personally don&#x27;t agree with the conclusions about &#x27;defense against nanotech attacks&#x27; outpacing the offensive capabilities.
