I AM, AS MOST READERS KNOW, GENERALLY A TECHNO-OPTIMIST. But mocking Elon Musk for his fears about Artificial Intelligence is silly.
The article might have interviewed James Miller for more on what Musk is talking about. Here’s my interview with Miller. Says Miller about strong AIs: “I think the default path is that they treat us horribly.” Also, “gray goo” isn’t a AI-gone-bad scenario, it’s a nanotechnology-gone-bad scenario, and a somewhat exaggerated one.

NANOTECHNOLOGY UPDATE: Novel multifunctional nanoparticle for diagnosis and therapy. “A variety of nanoparticles have been designed for multiple nanomedical purposes. An article at KurzweilAI.net presents news from UC Davis of a ‘nanoporphyrin’ platform for developing multifunctional nanoparticles based upon treelike dendrimer structures made using porphyrin, cholic acid, amino acids, and polyethylene glycol.”
Civilian technology, Joel Mokyr notes, has also gone “small” — nanotechnology, genetic engineering, custom-engineered materials, “mass customization” through 3-D printing. If the Rouge plant looming over Dearborn was the iconic symbol of the industrial age, the iconic symbol of our information age is the smartphone in your pocket.
“Large” technology requires the standardization of masses of people, centralized command-and-control, conformity to social norms. Massive work forces and massive armies cannot operate optimally otherwise.
“Small” technology enables individuals to make personal choices, fashion their world to their own dimensions, deploy their own talents and pursue their interests in ways of their own choosing. Standardization yields to customization.
President Obama doesn’t seem to get this. He sees history as a story of progress from minimal government to ever-larger government. He’s only sorry that he hasn’t taken us farther on that track.
But history doesn’t proceed in a straight line; it moves around. “Large” technology made big government seem necessary in 1914. “Small” technology requires something different, something more adaptive today.
Indeed. You could almost write a book about that.

OBJECTIFIED BY SOCIETY’S ARTIFICIAL STANDARDS: Hollywood Actors: Six-Packs That Speak Lines.
Via Outside the Beltway, I see that Men’s Journal has a lengthy article on what it takes to be a male movie star these days. The short answer: 3 to 4 percent body fat, an incredibly carved six-pack and lovingly sculpted musculature. Because that combination does not normally occur in nature, the long answer involves nutritionists, traveling weight trainers, and more-than-occasional injections of testosterone and human growth hormone.
In other words, a Hollywood star is not so much an actor, or a body. It is a nearly starving body that has been stripped of almost all its naturally occurring subcutaneous fat, then artificially bolstered with various supplements and medical technology to make it look like a statue rather than a famine victim.
Nanotechnology will take care of that, eventually, at which point, not being difficult and rare, the look will go out of style. Meanwhile, I’m reminded of this article from back when Salon didn’t suck.

NANOTECHNOLOGY UPDATE: Nanomotors are controlled, for the first time, inside living cells.
NANOTECHNOLOGY UPDATE: Nanoparticle pinpoints blood-vessel plaques: A step toward identifying plaques vulnerable to rupture that causes heart attack and stroke. “By loading the surface with gadolinium ions instead of injecting them and letting them flow freely in the blood stream, the nanoparticle increases the relaxivity — or contrast from healthy tissue — by more than 10,000 times. That’s because the nanorod carries up to 2,000 molecules of the contrast agent, concentrating them at the plaque sites. Secondly, attaching the contrast agent to a nanoparticle scaffold reduces its molecular tumbling rates and leads to additional relaxivity benefit, the researchers explained. While the view is better, they are able to use 400 times less of the contrast agent because it’s delivered directly to plaques.”
NANOTECHNOLOGY UPDATE: RNA nanotechnology – fewer structures in living cells than in test tubes.

FASTER PLEASE: World’s Smallest Pacemaker Can Be Implanted without Surgery.
Pacemaker surgery typically requires a doctor to make an incision above a patient’s heart, dig a cavity into which they can implant the heartbeat-regulating device, and then connect the pulse generator to wires delivered through a vein near the collarbone. Such surgery could soon be completely unnecessary. Instead, doctors could employ miniaturized wireless pacemakers that can be delivered into the heart through a major vein in the thigh.
On Monday, doctors in Austria implanted one such device into a patient—the first participant in a human trial of what device-manufacturer Medtronic says is the smallest pacemaker in the world. The device is 24 millimeters long and 0.75 cubic centimeters in volume—a tenth the size of a conventional pacemaker. Earlier this year, another device manufacturer, St. Jude Medical, bought a startup called Nanostim that makes another tiny pacemaker, and St. Jude is offering it to patients in Europe. This device is 41 millimeters long and one cubic centimeter in volume.
Doctors can implant such pacemakers into the heart through blood vessels, via an incision in the thigh. They use steerable, flexible tubes called catheters to push the pacemakers through a large vein.
It’s not nanotechnology, but it’s a great improvement.

NANOTECHNOLOGY UPDATE: Nanotubes aren’t stiff if they aren’t straight. “Materials scientists have pursued the question of why vertically aligned carbon nanotube forests show much lower modulus values than expected. Now researchers from Georgia Tech have found that the nanotubes they fabricate contain kinks that dramatically diminish modulus value. In other words, the nanotubes are not straight; therefore, they are not stiff.”

NANOTECHNOLOGY UPDATE: Two Types of Artificial Muscle From Nanotechnology.
The Wrap reports that in the film, titled Transcendence and based on a story by Jack Paglen, Johnny Depp “will play a scientist whose brain is uploaded into a supercomputer” while trying to create the first ever sentient computer. Nanotechnology and the Singularity are also said to play pivotal roles in the film, which explains the nerd boner you are currently sporting.
Johnny Depp may seem like a strange casting choice, but given his penchant for bizarre roles, we imagine he’ll play a mad scientist quite convincingly. He’ll be playing the main character, Will, who is assassinated by terrorists who are against technology. When his wife uploads his brain, Will begins to respond to her queries through the computer. By hooking his brain-cum-computer up to the Internet, he can continue his scientific research.
If anyone can pull that role off, it’s Depp.
