Do you have a problem with machine-phase? I'm all ears. Tell me why it<br>wouldn't work.<br></blockquote></div><br>I think some form of machine-phase is a fine idea. That doesn't imply a science fiction style matter duplicator. Remember the arguments between Drexler et al and Smalley et al, where Smalley's side pointed out that there's no such thing as a machine that can arbitrarily manipulate atoms (because the manipulator would have to be itself made of atoms), and Drexler's side replied that this doesn't mean we won't be able to do cool things with nanotechnology. Which is true, but it does mean that the early ideas about extremely general disassembler and assemblers are a thing of the past; today's designs are looking a lot more realistic - and a lot less like matter duplicators.
