Beredd att få ditt mind blown? Delar här med mig av en av de bästa bloggpostarna jag läst.
Det handlar om Artificiell intelligens och för att få en hum om vad det handlar om är här betydelsen hämtad från Wikipedia:
Artificiell intelligens (ASI) är intelligens som uppvisas av maskiner. De flesta AI-forskare och AI-läroböcker definierar detta område som ”studiet och utformningen av intelligenta agenter”, där en intelligent agent är ett system som är medveten om sin omgivning och vidtar åtgärder som maximerar sina chanser att lyckas. John McCarthy, som myntade begreppet 1955, definierar det som ”vetenskapen och tekniken att skapa intelligenta maskiner”.
Har försökt att bara ta med de bästa bitarna men det blev rätt så långt ändå.

Armed with superintelligence and all the technology superintelligence would know how to create, ASI would likely be able to solve every problem in humanity. Global warming? ASI could first halt CO2 emissions by coming up with much better ways to generate energy that had nothing to do with fossil fuels. Then it could create some innovative way to begin to remove excess CO2 from the atmosphere. Cancer and other diseases? No problem for ASI—health and medicine would be revolutionized beyond imagination. World hunger? ASI could use things like nanotech to build meat from scratch that would be molecularly identical to real meat—in other words, it would be real meat. Nanotech could turn a pile of garbage into a huge vat of fresh meat or other food (which wouldn’t have to have its normal shape—picture a giant cube of apple)—and distribute all this food around the world using ultra-advanced transportation.
Of course, this would also be great for animals, who wouldn’t have to get killed by humans much anymore, and ASI could do lots of other things to save endangered species or even bring back extinct species through work with preserved DNA. ASI could even solve our most complex macro issues—our debates over how economies should be run and how world trade is best facilitated, even our haziest grapplings in philosophy or ethics—would all be painfully obvious to ASI.
Kurzweil talks about intelligent wifi-connected nanobots in the bloodstream who could perform countless tasks for human health, including routinely repairing or replacing worn down cells in any part of the body. If perfected, this process (or a far smarter one ASI would come up with) wouldn’t just keep the body healthy, it could reverse aging. The difference between a 60-year-old’s body and a 30-year-old’s body is just a bunch of physical things that could be altered if we had the technology. ASI could build an “age refresher” that a 60-year-old could walk into, and they’d walk out with the body and skin of a 30-year-old. Even the ever-befuddling brain could be refreshed by something as smart as ASI, which would figure out how to do so without affecting the brain’s data (personality, memories, etc.).
A 90-year-old suffering from dementia could head into the age refresher and come out sharp as a tack and ready to start a whole new career. This seems absurd—but the body is just a bunch of atoms and ASI would presumably be able to easily manipulate all kinds of atomic structures—so it’s not absurd.
Kurzweil then takes things a huge leap further. He believes that artificial materials will be integrated into the body more and more as time goes on. First, organs could be replaced by super-advanced machine versions that would run forever and never fail. Then he believes we could begin to redesign the body—things like replacing red blood cells with perfected red blood cell nanobots who could power their own movement, eliminating the need for a heart at all. He even gets to the brain and believes we’ll enhance our brain activities to the point where humans will be able to think billions of times faster than they do now and access outside information because the artificial additions to the brain will be able to communicate with all the info in the cloud. The possibilities for new human experience would be endless.
Humans have separated sex from its purpose, allowing people to have sex for fun, not just for reproduction. Kurzweil believes we’ll be able to do the same with food. Nanobots will be in charge of delivering perfect nutrition to the cells of the body, intelligently directing anything unhealthy to pass through the body without affecting anything. An eating condom. Nanotech theorist Robert A. Freitas has already designed blood cell replacements that, if one day implemented in the body, would allow a human to sprint for 15 minutes without taking a breath—so you can only imagine what ASI could do for our physical capabilities. Virtual reality would take on a new meaning—nanobots in the body could suppress the inputs coming from our senses and replace them with new signals that would put us entirely in a new environment, one that we’d see, hear, feel, and smell.
Eventually, Kurzweil believes humans will reach a point when they’re entirely artificial; a time when we’ll look at biological material and think how unbelievably primitive it was that humans were ever made of that; a time when we’ll read about early stages of human history, when microbes or accidents or diseases or wear and tear could just kill humans against their own will; a time the AI Revolution could bring to an end with the merging of humans and AI. This is how Kurzweil believes humans will ultimately conquer our biology and become indestructible and eternal—this is his vision for the other side of the balance beam. And he’s convinced we’re gonna get there. Soon.
It’s clear that to be Friendly, an ASI needs to be neither hostile nor indifferent toward humans. We’d need to design an AI’s core coding in a way that leaves it with a deep understanding of human values. But this is harder than it sounds. For example, what if we try to align an AI system’s values with our own and give it the goal, “Make people happy”? Once it becomes smart enough, it figures out that it can most effectively achieve this goal by implanting electrodes inside people’s brains and stimulating their pleasure centers. Then it realizes it can increase efficiency by shutting down other parts of the brain, leaving all people as happy-feeling unconscious vegetables. If the command had been “Maximize human happiness,” it may have done away with humans all together in favor of manufacturing huge vats of human brain mass in an optimally happy state. We’d be screaming Wait that’s not what we meant! as it came for us, but it would be too late.
The system wouldn’t let anyone get in the way of its goal. If we program an AI with the goal of doing things that make us smile, after its takeoff, it may paralyze our facial muscles into permanent smiles. Program it to keep us safe, it may imprison us at home. Maybe we ask it to end all hunger, and it thinks “Easy one!” and just kills all humans. Or assign it the task of “Preserving life as much as possible,” and it kills all humans, since they kill more life on the planet than any other species.
The core final goal of a human being is to pass on his or her genes. In order to do so, one instrumental goal is self-preservation, since you can’t reproduce if you’re dead. In order to self-preserve, humans have to rid themselves of threats to survival—so they do things like buy guns, wear seat belts, and take antibiotics. Humans also need to self-sustain and use resources like food, water, and shelter to do so. Being attractive to the opposite sex is helpful for the final goal, so we do things like get haircuts. When we do so, each hair is a casualty of an instrumental goal of ours, but we see no moral significance in preserving strands of hair, so we go ahead with it. As we march ahead in the pursuit of our goal, only the few areas where our moral code sometimes intervenes—mostly just things related to harming other humans—are safe from us. Animals, in pursuit of their goals, hold even less sacred than we do. A spider will kill anything if it’ll help it survive. So a supersmart spider would probably be extremely dangerous to us, not because it would be immoral or evil—it wouldn’t be—but because hurting us might be a stepping stone to its larger goal, and as an amoral creature, it would have no reason to consider otherwise.
In this way, Turry’s not all that different than a biological being. Her final goal is: Write and test as many notes as you can, as quickly as you can, and continue to learn new ways to improve your accuracy. Once Turry reaches a certain level of intelligence, she knows she won’t be writing any notes if she doesn’t self-preserve, so she also needs to deal with threats to her survival—as an instrumental goal. She was smart enough to understand that humans could destroy her, dismantle her, or change her inner coding (this could alter her goal, which is just as much of a threat to her final goal as someone destroying her). So what does she do? The logical thing—she destroys all humans. She’s not hateful of humans any more than you’re hateful of your hair when you cut it or to bacteria when you take antibiotics—just totally indifferent. Since she wasn’t programmed to value human life, killing humans is as reasonable a step to take as scanning a new set of handwriting samples.
Turry also needs resources as a stepping stone to her goal. Once she becomes advanced enough to use nanotechnology to build anything she wants, the only resources she needs are atoms, energy, and space. This gives her another reason to kill humans—they’re a convenient source of atoms. Killing humans to turn their atoms into solar panels is Turry’s version of you killing lettuce to turn it into salad. Just another mundane part of her Tuesday. So Turry didn’t “turn against us” or “switch” from Friendly AI to Unfriendly AI—she just kept doing her thing as she became more and more advanced. What motivates an AI system? The answer is simple: its motivation is whatever we programmed its motivation to be.
