Logical succession, Part 2.

Last week the topic was Ray Kurzweil’s prediction that by 2030, not only would we send nanobots into our bloodstream by way of the capillaries, but they would target the neocortex, set up shop, connect to our brains and beam our thoughts and other contents into the Cloud (somewhere). Kurzweil is no crackpot. He is a brilliant scientist, inventor and futurist with an 86 percent accuracy rate on his predictions. Nevertheless, and perhaps presumptuously, I took issue with his prediction, but only because there was an absence of a logical succession. According to Coates,

“…the single most important way in which one comes to an understanding of the future, whether that is working alone, in a team, or drawing on other people… is through plausible reasoning, that is, putting together what you know to create a path leading to one or several new states or conditions, at a distance in time” (Coates 2010, p. 1436).1

Kurzweil’s argument is based heavily on his Law of Accelerating Returns that says (essentially), “We won’t experience 100 years of progress in the 21st century it will be more like 20,000 years of progress (at today’s rate).” The rest, in the absence of more detail, must be based on faith. Faith, perhaps in the fact that we are making considerable progress in architecting nanobots or that we see promising breakthroughs in mind-to-computer communication. But what seems to be missing is the connection part. Not so much connecting to the brain, but beaming the contents somewhere. Another question, why, also comes to mind, but I’ll get to that later.

There is something about all of this technological optimism that furrows my brow. A recent article in WIRED helped me to articulate this skepticism. The rather lengthy article chronicled the story of neurologist Phil Kennedy, who like Kurzweil believes that the day is soon approaching when we will connect or transfer our brains to other things. I can’t help but call to mind what one time Fed manager Alan Greenspan called, “irrational exuberance.” The WIRED article tells of how Kennedy nearly lost his mind by experimenting on himself (including rogue brain surgery in Belize) to implant a host of hardware that would transmit his thoughts. This highly invasive method, the article says is going out of style, but the promise seems to be the same for both scientists: our brains will be infinitely more powerful than they are today.

Writing in WIRED columnist Daniel Engber makes an astute statement. During an interview with Dr. Kennedy, they attempted to watch a DVD of Kennedy’s Belize brain surgery. The DVD player and laptop choked for some reason and after repeated attempts they were able to view Dr. Kennedy’s naked brain undergoing surgery. Reflecting on the mundane struggles with technology that preceded the movie, Engber notes, “It seems like technology always finds new and better ways to disappoint us, even as it grows more advanced every year.”

Dr. Kennedy’s saga was all about getting thoughts into text, or even synthetic speech. Today, the invasive method of sticking electrodes into your cerebral putty has been replaced by a kind of electrode mesh that lays on top of the cortex underneath the skull. They call this less invasive. Researchers have managed to get some results from this, albeit snippets with numerous inaccuracies. They say it will be decades, and one of them points out that even Siri still gets it wrong more than 30 years after the debut of speech recognition technology.
So, then it must be Kurzweil’s exponential law that still provides near-term hope for these scientists. As I often quote Tobias Revell, “Someone somewhere in a lab is playing with your future.”

There remain a few more nagging questions for me. What is so feeble about our brains that we need them to be infinitely more powerful? When is enough, enough? And, what could possibly go wrong with this scenario?

Next week.
