Will Octobot Transform Medicine?

Acclaimed futurist Ray Kurzweil has a lot of bold predictions (including that computers will become smarter than us within a few decades), and some of his most interesting ones deal with how technology -- especially nanotechnology -- will soon totally revamp how we manage our health, leading to longer, healthier lives and hugely increased intelligence. Sounds like science fiction, right? Meet Octobot. Harvard researchers have unveiled what they describe as the "first autonomous, entirely soft robot," which they call Octobot (it has eight arms, like an octopus). It has no metal, no battery, no electronics of any sort, yet manages to move under its own power. It uses a "microfluidic logic circuit" rather than a circuit board to control the movements of its arms and to power itself along, using gas reactions...
