Genetic Coding, Synthetic Brains, and Publicity
First, a brilliant (aren’t they all) TED talk by Dr. Fineberg, who explains some of the potential right around the corner for genetic rewriting. Interestingly, I think the question that he repeatedly asks is also the answer to critics who suggest that there will be an enormous (and bloody) opposition to superhumans (or transhumans, or whatever your preferred term is): “If the technology existed to allow you to live another 100 years, wouldn’t you want to?”
For me, the answer is clearly yes. Moreover, I don’t see many other people saying no. In a modern context, there are groups who refuse medical treatment (and other technological progress) for moral or religious reasons: the Amish are the most explicit example, but many other people refuse blood transfusions, medical treatment, or choose not to get an abortion because the science doesn’t align with their morals or religious views. Except for abortion, the protests are largely silent and don’t get in the way of the rest of us getting out transfusions or treatment. Hardly anyone protests people wearing eyeglasses, or taking insulin, or even getting brain-to-computer implants that allow victims of various full body paralysis disorders to communicate. It seems to me that the main reason for that is that everyone (or substantially everyone) at the end of the day -wants- to live longer, healthier, more fulfilling lives. And science, through genetic coding and mechanical augmentation, lets us do that.
Note, however, the eugenics undertones in his talk: In this sense I think the ideas in my earlier post remain plausible when genetic coding is restricted to diseases for the unborn (though Dr. Fineberg doesn’t necessarily agree that we should do that) or at least when adults can rewrite their own code ‘on the fly’ while alive (that is, code changes aren’t limited to the developing human but can be performed on already alive people.)It is, to be fair, a fine ethical line and one upon which reasonable people can disagree.
Dr. Fineberg’s talk is below, though I encourage you to visit TED to see other brilliant (but not necessarily futurist) talks.
Second, Science Daily comes through with an article explaining how carbon nanotubes might be used to create synthetic synapses; the building blocks of brains. Two things about this article jump out at me. First, the timeline. In 2006 people at USC started wondering if we might create a synthetic brain. Five years later, they’ve created artificial synapses. That’s a pretty quick turnaround, even by today’s standards. Second, the numbers. According to the article the human brain has something on the order of 100 Billion neurons, and each neuron is comprised of some 10,000 synapses. By my fuzzy math, that means we’d need something on the order of 1 Quadrillion (10^15) carbon nanotubes to recreate the structure of the human brain. I hope we can make these in big batches!
Finally, a little shameless self-promotion. Although I have a ‘going public’ post, as of today I’m officially branching out through social media groups. So, if you’re new here, I encourage you to leave your thoughts and, if you enjoy what you read, share with your friends.
