These computer simulations try only to duplicate the interactions between the cortex and the thalamus. Huge chunks of the brain are therefore missing. Dr. [Dharmendra] Modha understands the enormity of his project. His ambitious research has allowed him to estimate what it would take to create a working model of the entire human brain, and not just a portion or a pale version of it, complete with all parts of the neocortex and connections to the senses. He envisions using not just a single Blue Gene computer [with over a hundred thousand processors and terabytes of RAM] but thousands of them, which would fill up not just a room but an entire city block. The energy consumption would be so great that you would need a thousand-megawatt nuclear power plant to generate all the electricity. And then, to cool off this monstrous computer so it wouldn’t melt, you would need to divert a river and send it through the computer circuits.
It is remarkable that a gigantic, city-size computer is required to simulate a piece of human tissue that weighs three pounds, fits inside your skull, raises your body temperature by only a few degrees, uses twenty watts of power, and needs only a few hamburgers to keep it going.[/b]
Thanks to God, right? And, with any luck, ours.
…when a person tells a lie, he simultaneously has to know the truth, concoct the lie, and rapidly analyze the consistency of this lie with previously known facts.
Let’s just file this one under, “no sweat”.
As Sir William Osler once said, “The philosophies of one age have become the absurdities of the next, and the foolishness of yesterday has become the wisdom of tomorrow.”
Meanwhile the fucking objectivists still come and go.
I once wrote a biography of Albert Einstein, called Einstein’s Cosmos, and had to delve into the minute details of his private life. I had known that Einstein’s youngest son was afflicted with schizophrenia, but did not realize the enormous emotional toll that it had taken on the great scientist’s life.
From the Big Bang to schizophrenia. Go figure.
Using MRI scans, scientists can now read thoughts circulating in our brains. Scientists can also insert a chip into the brain of a patient who is totally paralyzed and connect it to a computer, so that through thought alone that patient can surf the web, read and write e-mails, play video games, control their wheelchair, operate household appliances, and manipulate mechanical arms. In fact, such patients can do anything a normal person can do via a computer.
Right, and who foots the bill?
One day, would it be possible to walk through walls? To build starships than can travel faster than the speed of life? To read other people’s minds? To become invisible? To move object with the power of our minds? To transport our bodies instantly through outer space?? Since I was a child , I’ve always been fascinated by these questions.
And [of course] as with the rest of us, he will no doubt no to the grave, shall we say, unapprised.
