There is a vast difference between logically possible and empirically plausible. The simultaneous mastery of miniaturization and complexity involved in creating a single nanobrain capable of both explicit self-awareness and continuous self-modification in response to environmental input while maintaining such a self-referential conscious identity would of necessity dwarf the totality of human technical achievement from stone age to present. Drexler's article reads like excellent speculative fiction, but imagination, no matter how superb, does not automatically lead to manifestation or reification.
