Just Looking ...

I came across the following article on BBC World. It deals with nanotechnology, specifically with the creation of 'a tiny chemical brain' that will be able to control multiple nano machines at the same time. The aim is that one day the brains "may be able to guide the nanobots through the body and control their functions". Reading this article made me think of Dr. Sagman's lecture on 'How Nanotechnology Will Change the World'. This invention reinforces the claim of this technology's revolutionary capabilities in all spheres of our lives. If a nano brain, albeit a simple one, is createable, then how soon will it be until highly complex systems are created? Is it conceivable that through breakthroughs in the research put forth by this article,  highly complex robots could be created, outfitted with sophisticated reactions and pseudo-thought? My mind is drawn to the phrase 'the faceless horde' from the lecture on cloning. If science is able to create a brain, then arguably, the concept of robotic armies with the same programmed aims, moving as one and responding intelligently is no longer purely in the fantasy realm of science fiction.
