OK, so perhaps this should have been the first post of this category, since it is arguably the top project at the intersection of cognitive science and artificial intelligence. Yes, by “Blue” I am referring to Henry Markam’s Blue Brain project, started back in 2005. What we encounter in the Blue Brain project is nothing less than a possibility of a simulated “consciousness” and other complexities of the brain (although only on the level of a rat’s at the moment, and at 1/10th of its speed), approached from the other side of computation, namely by creating individual neurons instead of the more common top-down approach in grammatical computing — the revolution of third wave cybernetics, as Katherine Hayles would have put it.
Even the strong AI skeptic John Searle in one of his lectures commented that , even though the mind is not a software, and the brain is not a supercomputer, the computer may be constructed as such to simulate the brain. He denies by all means the grammatical approach to consciousness with his famous Chinese Room argument, but he never did deny semantic approaches, only stating that such approach is not yet possible. But with the Blue Brain — although this project leans towards cognitive science instead of AI — such an approach is, at least, on the horizon of possibility.
You can read more extensively about the Blue Brain and its progress here and here, but now let us continue on to our analysis. What do we have here with the Blue Brain is no less a science simulating the full complexity of a mind, right down (or, rather, up from) its neuron basis. How do we integrate this into our cognitive mapping? What we need to understand first and foremost is how this project requires an understanding that, 1) the mind comes from a whole, not of any one of its parts, and therefore, 2) non-localizable to any kernel whatsoever.
This, of course, is what Slavoj Žižek, in his The Parallax View, called “the unbearable lightness of being no one”. Are we not, today, with cognitive science, confronted with the fact, already acknowledged with Hume, that the subject does not exist? In today’s context, however deep we pry open the skull and dig the brain, we find nobody home, no kernel of the soul, no subject. This is the paradox of the 21st-century narrative of the subject.
What the Blue Brain project provides is no less than a common ground for us to think about silicon-based versus carbon-based life — whereas before, we see carbon-based life as evolving, as beings whose consciousness comes later, silicon-life were beings programmed through “consciousness” (grammatical understanding of the relations of objects, etc. — which is where I suspect the true “uncanny valley” lies). Artificial Life provided a change by introducing chaos and emergence into the foray, but did not necessarily look into complex nervous systems. If and when the Blue Brain project succeeds, what we will have is no less than a complete brain simulation of a species, a silicon-based brain, “comparable to the Human Genome Project,” as Markam put it on the link above.
While I remain an agnostic to the Moravecian idea of downloading minds into computers (and totally an atheist apropos the idea that the subject will remain the same), I do believe that the Blue Brain project and its completion will require us to rethink our subjectivity and humanity as a whole. Silicon-based and carbon-based life will have a fully similar grounding, and so many new spaces of cognitive science will open up, as well as new spaces of transhumanity and ubiquitous technology. All of us will have to confront not only the fact that there is nobody home, but also that home is temporary, shredding every last bit of our humanistic grounding — the unbearable lightness of being Blue.
If (and possibly when) the Brain is implemented into a body, then things will go much further. Thoughts? Feel free to comment away!
