I agree, in the long-term, big-picture, distributed eye and hand is important. e.g. Although relativity could have been deduced from the evidence, first you have to obtain that evidence, by the action of constructing observation devices. But there's nothing to stop centralized computing from having distributed terminal-like i/o devices, cameras and waldos. A cognitive argument for distribution is that a diversity of ideas, developed somewhat in isolation, using their local unique observation and unique action, is more likely to innovate. Many points of view will see more. However, this can be simulated with internal divisions.
