Quantum Internet Search
"JB immediately tossed me in a corner of the restaurant with Sergey Brin and Larry Page, who grilled me on the potential applications of quantum computation. They were shockingly knowledgeable on the subject and quickly pushed me like a novice sumo wrestler to edge of the ring that marks the boundary between the known and the unknown. That boundary is always closer than one thinks.
We agreed that quantum internet searches are a few years off. I had spent the afternoon in Jeff Kimble's lab at Caltech contemplating the first node of the the quantum internet — a single atom trapped in an optical cavity, capable of exchanging entangled photons with any other nodes, as soon as they are brought into existence. But when the quantum internet has only one node, containing one bit, Q-Google (Quoogle?) is not yet necessary. Sergey and Larry and I noted that when it is up and running, the quantum internet should offer all sorts of wacky possibilities for quantum internet search. Searches could be made significantly more efficient, for example, by using quantum parallelism to explore every node of the quantum internet simultaneously. Problems arise, however, from the fact that quantum bits can't be cloned. I cannot go further into our discussion as that would involve proprietary information concerning quantum internet protocols (e.g., Q-TCPIP).
Sergey broached the subject of massive entanglement and decoherence, a hot topic in quantum information these days (Entanglement is a peculiarly quantum-mechanical effect in which a bunch of quantum systems such as atoms share more information with each other than is possible classically. Entanglement is the branch of quantum weirdness that allows quantum computers to function. Decoherence is a process that destroys entanglement. As I said, these guys were really on top of their quanta).
We discussed recent experiments that Dave Cory and I had done at MIT, and Sergey made a rather fine suggestion for an experiment to test whether gagillions of entangled nuclear spins decohere faster than gagillions of unentangled nuclear spins. Dave and I will check it out.
At this point Jeffrey Epstein joined the conversation and demanded to know whether weird quantum effects had played a significant role in the origins of life. That question pushed me way out of the sumo ring into the deep unknown. We tried to construct a version of the question that could be answered. I was pushing my own personal theory of everything (the universe is a giant quantum computer, and to understand how things like life came into existence, we have to understand how atoms, molecules, and photons process information). Jeffrey was pushing back with his own theory (we need to understand what problem was being solved at the moment life came into being). By pushing from both sides, we managed to assemble a metaphor in which molecules divert the flow of free energy to their own recreational purposes (i.e., literally recreating themselves) somewhat in the way Jeffrey manages to divert the flow of money as it moves from time-zone to time-zone, using that money for his own recreational purposes (i.e., to create more money). I'm not saying it was the right way to describe the origins of life: I'm just saying that it was fun."

Ghost in the Shell: Innocence
Set in 2032, when the line between humans and machines has been blurred almost beyond distinction. Humans have virtually forgotten what it means to be entirely human in both body and spirit, and the few humans that are left coexist with cyborgs (human spirits inhabiting entirely mechanized bodies) and dolls (robots with no human elements at all).
Batou is a cyborg. His body is artificial: the only remnants left of his humanity are traces of his brain…and the memories of a woman called The Major.
A detective for the government’s covert anti-terrorist unit, Public Security Section 9, Batou is investigating the case of a gynoid—a hyper-realistic female robot created specifically for sexual companionship—who malfunctions and slaughters her owner.
As Batou delves deeper into the investigation, questions arise about humanity’s need to immortalize its image in dolls. Together, Batou and his partner must take on violent Yakuza thugs, devious hackers, government bureaucrats and corporate criminals to uncover the shocking truth behind the crime."
Some words from Mamoru Oshii (Director/Screenwriter):
"This movie does not hold the view that the world revolves around the human race. Instead, it concludes that all forms of life—humans, animals, and robots—are equal. In this day and age when everything is uncertain, we should all think about what to value in life and how to coexist with others. We all need friends, family, and lovers. We can’t live alone. In the year 2032, when this movie takes place, robots and electronic beings have become necessary companions to people. Actually, that time has come already. What we need today is not some kind of anthropocentric humanism. Humanity has reached its limits. I believe that we must now broaden our horizons and philosophize about life from a larger perspective. With this film, I hope to reflect upon the uneasiness that pervades the world today. Under such conditions, what is the meaning of human existence?"

Asia's Growth
Link
Source: World Economic Forum Weblog
"China is fast becoming a competitor with India for technological development."
"After two decades of pursuing high-tech investment, China is now home to dozens of R&D centres of multinationals – a phenomenon that has led to suggestions that China is competing with India as the technology hub of Asia. Almost all the global giants in automobile, telecommunications technology, computer, software, machinery, electronics, biotechnology, pharmaceuticals and other major industries have made such high-tech investments in China. These companies include General Electric (GE), General Motors, P&G, Unilever, Microsoft, Intel, IBM, Motorola, Siemens, Ericsson, Nortel, AT&T, Lucent Bell and Samsung."

Small wars: Nanotechnology is on the verge of creating a global revolution
As both a science and application, nanotechnology is on the verge of creating a global revolution for many industries. Large amounts of funding are needed to jump-start the technology from laboratory to commercialisation – money from federal or state sources, grants and venture capital. Consequently, despite the hype, true nanotech companies do not yet abound."

SciFi.com and HDTV
"Yes, HDTV is the wave of the future and I'm positive the SCI FI Channel will eventually convert, but, unless you somehow haven't noticed (which I doubt, since you own one), HDTVs are still very expensive, and many people don't have the resources to buy them. When given the choice between $350 for a 27-inch flat-screen TV and up to $5,999 for an HDTV (some are even higher in price), most people will go for the $350 flat screen."
Low-Quality TV Doesn't Deserve HD
"I have long thought that the SCI FI Channel should make every effort to join the HDTV world ('SCI FI Should Broadcast in HD'); but then I reconsidered, thinking over exactly what they offer to the viewing public most of the time.
Theodore Sturgeon coined a famous maxim which goes: 90 percent of everything is crap. Sadly, that is more than true for the SCI FI Channel. For every Stargate SG-1, Stargate Atlantis, Farscape and Invisible Man, we get get entire warehouses of straight-to-video (or is it straight to DVD by now?) crap.
If they don't care about the low-quality of the majority of their programming, why would they care about their signal quality?"
HDTV Is Tech Snobbery
"Lots of us in the sci-fi demographic are very much into high-tech, but that does not necessarily mean that we value television so much that we'll sink four-digit amounts to watch HDTV."
