Re-Evolving Mind, Hans Moravec, December 2000 Computers have permeated everyday life and are worming their way into our gadgets, dwellings, clothes, even bodies. But if pervasive computing soon automates most of our informational needs, it will leave untouched a vaster number of essential physical tasks. Construction, protection, repair, cleaning, transport and so forth will remain in human hands. Robot inventors in home, university and industrial laboratories have tinkered with the problem for most of the century. The first electronic computers in the 1950s did the work of thousands of clerks. But things are changing. The short answer is that, after decades at about one MIPS (million instructions (or calculations) per second), computer power available to research robots shot through 10, 100 and now 1,000 MIPS starting about 1990 (Figure 1). It was a common opinion in the AI labs that, with the right program, readily available computers could encompass any human skill. It's easy to explain the discrepancy in hindsight.
Brain imaging can predict how intelligent you are, study finds (Medical Xpress) -- When it comes to intelligence, what factors distinguish the brains of exceptionally smart humans from those of average humans? As science has long suspected, overall brain size matters somewhat, accounting for about 6.7 percent of individual variation in intelligence. More recent research has pinpointed the brain’s prefrontal cortex, a region just behind the forehead, as a critical hub for high-level mental processing, with activity levels there predicting another 5 percent of variation in individual intelligence. Now, new research from Washington University in St. Published in the Journal of Neuroscience, the findings establish “global brain connectivity” as a new approach for understanding human intelligence. “Our research shows that connectivity with a particular part of the prefrontal cortex can predict how intelligent someone is,” suggests lead author Michael W.
Goertzel Contra Dvorsky on Mind Uploading Futurist pundit George Dvorsky recently posted an article on io9, labeled as “DEBUNKERY” and aimed at the topic of mind uploading. According to the good Mr. Dvorsky, “You’ll Probably Never Upload Your Mind into a Computer.” He briefly lists eight reasons why, in his view, mind uploading will likely never happen. UPDATE - here is a video interview on this subject: Note that he’s not merely arguing that mind uploading may come too late for you and me to take advantage of it – he’s arguing that it probably will never happen at all! The topic of Dvorsky’s skeptical screed is dear to my heart and mind. Every one of Dvorsky's objections has been aired many times before – which is fine, as his post is a journalistic article, not an original scientific or philosophic work, so it doesn’t necessarily have to break new ground. In this article I will briefly run through Dvorsky’s eight objections, and give my own, in some cases idiosyncratic, take on each of them. But, whatever…. So what? True enough.
Who’s conscious? A recent meeting of neuroscientists tried to define a set of criteria for that murky phenomenon called “consciousness”. I don’t know how successful they were; they’ve come out with a declaration on consciousness that isn’t exactly crystal clear. It seems to involve the existence of neural circuitry that exhibits specific states that modulate behavior. The neural substrates of emotions do not appear to be confined to cortical structures. This is where they’re losing me. They seem to have reached an agreement that a mammalian neocortex is not necessary for consciousness, which seems entirely reasonable to me. Anyway, here’s their conclusion. We declare the following: “The absence of a neocortex does not appear to preclude an organism from experiencing affective states. Wait, I missed something again. Also, here is an interesting summary of evidence for sophisticated intentional behaviors in octopus. The octopus is the only invertebrate to get a shout-out at all.
How Self-Replicating Spacecraft Could Take Over the Galaxy I'm going to re-post here a previous comment I made on this subject, because I think it's worth repeating. Any alien civilization that is sufficiently developed enough to span the cosmos, will be so far advanced from us, that we would not be able to even comprehend their technology and in turn they probably wouldn't even recognise us as a sentient intelligent species. I've always found the "Well if there are aliens why haven't they said hello?" argument to be far too arrogant. There are islands all over the oceans of our world that are nothing more than rocks sticking out of the water with bacteria on them. That's us, the barren rock. The alien probes have probably been through out solar system many times (we'd never know) looked at our skyscrapers, cities and agriculture.
Scientists Successfully ‘Hack’ Brain To Obtain Private Data By Peter V. Milo August 25, 2012 1:56 AM News Get Breaking News First Receive News, Politics, and Entertainment Headlines Each Morning. Sign Up BERKELEY, Calif. Researchers from the University of California and University of Oxford in Geneva figured out a way to pluck sensitive information from a person’s head, such as PIN numbers and bank information. The scientists took an off-the-shelf Emotiv brain-computer interface, a device that costs around $299, which allows users to interact with their computers by thought. The scientists then sat their subjects in front of a computer screen and showed them images of banks, people, and PIN numbers. The P300 signal is typically given off when a person recognizes something meaningful, such as someone or something they interact with on a regular basis. Scientists that conducted the experiment found they could reduce the randomness of the images by 15 to 40 percent, giving them a better chance of guessing the correct answer.
How to build a Dyson sphere in five (relatively) easy steps If you have energy, you can launch as much mass as you want into space. If you have enough mass, you have a radiation shield, and with the energy from your swarm, you can spin that mass for gravity. These are not issues. Well we could live on Earth and just keep the dyson swarm inside the orbit of Mercury. Of course our planet would be in perpetual darkness then but that's an exercise left to the student. Problems I see with launching mass to block radiation is that mass would block ALL radiation including visible light. Where does that mass come from? Even if you do build structures large enough to support humans for extended periods of time, and you spin them to create centrifugal force (not gravity), that doesn't solve the radiation issue. Not everything is based on energy production, as you wrote above. Also, as other commenters have pointed out, if we direct the energy from these swarms to Earth, something has to be done with it.
