I have admired Philip Moriarty since I first saw a video of a nanotechnology debate at Nottingham University taped in 2005 in which Moriarty stood up and asked some pretty pointed questions to some of the panel members who were proposing molecular nanotechnology (MNT). (The nearly two-hour video I have included below).
The tenor of Moriarty’s questions and comments are exemplified by this comment: “To date there has not been a single mechanosynthesis experiment, in that the most basic step in terms of abstracting a hydrogen atom from a diamond surface has not been done. That has to be proved in order to demonstrate the viability of the machine approach. I’ve never been able to square that with the statement that there are no showstoppers—not one experiment has been done, correct?
I’m not sure he received an answer to that question. It’s likely he was told that Freitas and Merkle had run some computer model simulations.
