What follows is a cleaned-up, link-infused conversation I recently had with a biologist friend and practicing Luddite:
Adam: I saw Molly the other day, not quite Chomsky, but close.
Adam: Yeah, now I'm here in Parkland eating some oatmeal squares.
me: I bought your book the other day. Not quite Chomsky, but close.
Adam: oh really? So you're the one.
me: Yeah, it's in the mail...so don't ask any questions, but I'm sure it's a regular tour-de-force.
Adam: Yeah dude.
me: Hey, I found the anti-Adam.
Adam: You found what?
me: Ray Kurzweil.
Adam: Too late!!! Already knew about the Great D******bag and his coming singularity.
me: So you're in, yeah? We take off next week.
Adam: Oh yeah, transhumanism and the whole schebang!
me: A friend over here gave me one of his books.
Adam: What a gomer, huh?
me: My friend's Canadian...but Ray, yeah: pipe-dreams in print.
Adam: It's a good idea to study the rate of technological change but he gets some things so wrong.
me: I agree with his accelerating returns from technology...but I'm pretty sure he looses all ground with his blinding optimism.
Adam: Yeah, but not just that. When he plotted human achievement in the line of cosmic and biological evolution my head exploded. He made a really basic mistake evolution is not exponential and never will be.
me: Well, he slips in memetic evolution as the exponential part. But I think he had it a bit backwards.
Adam: You know the Fermi paradox? Between the number of planets and galaxies and time, if a technological singularity was inevitable it should have already happened. But of course…it hasn't...
me: Is that the one in reaction to Carl Sagan's argument for ET life?
Adam: I think so. It's not a direct refutation of Kurzweil but it's suggestive.
me: Kurzy also misses the growing and absolutely irrefutable tension between our biology and our technology. I thought this was his grossest error. I mean, people in "developing nations" are unbelievably less likely to have mental illness, or stress related problem, and even drug addiction. Sure they might be starving and we can't seem to find an alternative to join-us-or-die capitalism, but there's an undeniable link between pace and complexity (which Kurzy exalts) and Huge Societal Problems.
Adam: Yep. We're still a bunch of apes.
me: I want to be bonobo.
Adam: I've been reading a lot of junk on language and how it turned up in the first place. At Kurzweil's pace of evolution, we're due-up for another ground-breaking advancement like language.
me: If you're interested in language stuff, check out Steven Pinker. Brilliant stuff. He's one of the few than run a psychology tack without sacrificing the linguistics.
Adam: Oh yes, I've watched Pinker.
me: He's cool-looking too, right?
Adam: I've got this penchant for stalking cool people on the internet and pacing my room listening to their talks.
me: Oh! We're studying all about qualia in a philosophy class. Crock of shit...basically...
Adam: Yeah, qualia is bullshit.
Adam: I listen to Pinker, Dennett, Chomsky, Jackendoff and the rest.
me: Yeah, Dennett has a pretty home-run argument against qualia.
Adam: Good, it deserves it. You know, you might like my little book.
me: I'm excited to get it.
Adam: It doesn't directly apply to consciousness but it toys with at least one implication.
me: If I cite it...I'll let you know.
Adam: Here's a line from it: "I am increasingly convinced that the real division in the intellectual arena is not between selfish ideologies but between two opposite poles separated by their stance on information flow. One pole claims the human minds as an autonomous source of information and the other sees it as a recipient."
me: Interesting. The "current state" of cognitive science is increasingly "postcognitivist", which basically breaks cognition from the traditional view of purpose-built sub-systems -- the view that we're computers that process input and provide output -- and forms a new one where we're walking accidents of thought. Hah!
Adam: I could see that. Is there any space for computation in this view? Is computation just another subsystem?
me: Well, that might be good traditionalist defense. The new guard kind of hold that when we say, see a baseball coming towards us, we aren't computing anything. Instead, we have an experience, informed by our history of sensorimotor experience that tells us, rather simply, to deal with the situation. (Catch it or get out of the way.) The can of worms is really in embedded cognition which is the view that we use our world and our bodies as our cognitive system...not just our brains. So then we've this recurrent problem of interaction-as-cognition. It gets a bit hairy, but really interesting. And it really draws a useful line in the sand between cognitive science and psychology. (Which in my opinion should admit that it's a clinical discipline and hand the theoretical torch off to cognitive and neuroscience.)
Adam: So wait, if the "conscious" aspect of consciousness is epiphenomenol, how could evolution have shaped it, or is the point that it never has?
me: I suppose that's a really good question. But it's kinda like a lot of evolution: consciousness wasn't useful until it was accidentally made available by an organized brain. Hofstadter has wonderfully human and respectfully emotive ways of putting this stuff.
Adam: Read this. It's cool, though certainly might already know about it, but Doug's even got something to say about Kurzweil.
me: Cool, I will, but I got run to the store before it closes.
Adam: Good talking.
