szczys writes: Feynman predicted that we would some day "swallow the doctor" and to some extent that is already happening. There are cameras in pill-form that the patient swallows to monitor the digestive tract, and pacemakers are now inserted via catheter rather than major surgery. The question is: where are we going with robots we can put inside our bodies? Intuitively it seems far away, but there is already an open source platform for capsule robots. Medical devices are where the money's at when it comes to hardware development. We can expect to see a lot of work in the coming years to make the man-machine hybrid something that is much more organic, sprinkled with small tablets of robot.
