Eric Drexler has said that a promising path to the assembler
breakthrough could occur if we managed to manipulate polymer/protein
self-assemblers with greater sophistication. I'm no expert in this
area, but this breakthrough looks like a step towards the realization of
a nano-assembler. Could anyone comment?
