World Future Review: What does it mean to build “new and improved” human intelligence? And where are we in terms of bringing this to reality?
Kurzweil: There are two components must be achieved to create a human-level artificial intelligence.
First, the hardware capacity of the human brain and, second, emulating the brain’s own software techniques.
There are a number of different ways to analyze what the hardware requirements are. If you take the most conservative analysis, which is 1016 calculations per second [10 million billion calculations per second or 10 billion MIPS], we’ll actually have that by next year in a supercomputer and we’ll have it for about $1000 by 2020. By 2029, that level of computation will be very inexpensive....
But the goal is not just to create a simulation. The actual goal is to understand how it works, understand its basic principles. That’s the software. We can engineer systems that don’t have the restrictions of a human brain, which, for example, has to fit into a less than one cubic foot skull that runs on a chemical substrate that sends messages at a few hundred feet per second (which is a million times slower than electronics), that computes at a mere 200 calculations per second, and so on. We won’t be limited to a billion pattern recognizers in the cerebral cortex—we could have a trillion. And if we understand the basic principles by which the brain creates intelligent behavior, we can focus and leverage it and create much more powerful systems.
I’m actually writing a new book to amplify that case called How the Mind Works—and How to Build One, which will talk about the tremendous progress since The Singularity Is Near came out in 2004 in this reverse-engineering project. Human level intelligence in machines is not going to displace us, compete with us, it’s not an invasion coming from Mars—these are tools we’re creating to basically expand ourselves, who we are. And that’s what we’ve done with tools since we’ve had tools. Ever since we picked up a stick to reach a higher branch, we’ve used it to extend our reach—the things we couldn’t otherwise do. First physically and now mentally.
World Future Review: What are the most pressing environmental issues that we should be concerned about as we move forward? And in a world where nanoengineered photovoltaic panels have eliminated fossil fuels, what will our obligation to the environment be?
Kurzweil: The first industrial revolution technologies were a compromise. They are harmful to the environment. Like, for example, fossil fuels. We are running out of energy if we limit ourselves to 19th century technologies like fossil fuels, but obviously we don’t need to do that.
We have the opportunity to move away from fossil fuels. Solar has the most headroom but there are others … [for example,] there’s also a tremendous amount of geothermal energy. There are many different renewable, decentralized, environmentally-friendly technologies that ultimately will be extremely inexpensive. There’s a 50% deflation rate to information technology (an implication of the law of accelerating returns). It’s actually about 25% in the case of solar energy—a 25% deflation rate each year—but that means that it ultimately will be very inexpensive—much less expensive than comparable fossil fuels—and it has the added advantages of being environmentally-friendly and decentralized, unlike today’s supertankers and nuclear power plants, which are centralized and therefore vulnerable to catastrophic centralized destruction. New technologies in general are decentralized, and that makes them safer. The Internet is decentralized—if a piece of it goes down, the information just routes around it.
Over the next one or two decades, there will be another food revolution. We’ll go from horizontal agriculture, which has dominated humanity for the last several thousand years, to vertical farming—basically, computer-controlled factories creating hydroponic plants for fruits and vegetables and in vitro-cloned meat, which could be engineered to be much healthier. [For example,] you could have beef with Omega 3 fats rather than saturated fat.
Same thing for housing. There’s an emerging industry of three-dimensional printing. Right now, the key features are at the microscale, but within 20 years, it will be at the nanoscale and we’ll be able to print out three-dimensional objects of extreme complexity. Today, we can print out modules to build inexpensive housing that’s very sturdy, earthquake proof, and basically snap them together Lego-style. These little modules have all the pipes and communication lines built in. One of the projects at Singularity University was to use three-dimensional printing to create low-cost housing for the developing world. We can house people very comfortably if we convert resources in the right way. Ultimately, with nanotechnology being able to produce inexpensive modules for houses as well as everything else we need, we’ll be able to do that at very low cost.
World Future Review: You recently said in a interview with H+ Magazine, “whereas we can articulate technical solutions to the dangers of biotech, there‘s no purely technical solution to a so-called unfriendly AI. We can‘t just say, ‘We‘ll just put this little software code sub-routine in our AIs, and that‘ll keep them safe.’ I mean, it really comes down to what the goals and intentions of that artificial intelligence are. We face daunting challenges.” In THE FUTURIST in 2006, you acknowledged that unlike nanotechnology, “superintelligence by its nature cannot be controlled.” Can you elaborate a little more on the risks and dangers? Also, given those risks and dangers, if there’s no real way to safeguard things from a dystopian scenario, why is strong AI desirable?
Ray Kurzweil: I don’t think we should envision it with a model of, someone’s going to create this Strong AI in a laboratory and unleash it on the world. That’s not the way it’s going to happen. We have hundreds of examples today of Narrow AI—programs doing tasks that used to be done by human intelligence but doing them better and less expensively—and the narrowness is gradually getting less narrow. And this intelligence is deeply integrated with our own already, even if, for the most part, it’s not yet in our bodies and brains. There’s going to be a continuous exponential progression of computers getting more powerful, getting smaller, and we’re going to become more and more integrated with them. And they’ve already made us smarter, and I don’t just mean as measured by IQ tests. I mean by measurement of intellectually capability of our civilization, which includes all of the things that we can do with biological and non-biological intelligence working together.
That integration is going to become more and more intimate. In 2035, you’re not going to be able to walk into a room and say, “humans on the right side, machines on the left.” It’s going to be all mixed up and integrated—one complex, dynamic, chaotic human/machine civilization. Gradually over time, the nonbiological portion of humanity’s intelligence is going to grow exponentially. The biological portion is fixed. It’s really not going to change—not to any significant degree. So, over time, nonbiological technology will predominate. But it’s still going to be one civilization with people having different philosophies and arguing about values.
I would maintain we actually have much more consensus on human values than might appear. People focus on our differences and talk about culture wars, and yes, there are certain issues, but what we all agree on is actually much more pervasive than what we disagree on. This includes a belief in progress. The idea of progress is a fairly recent concept in human history. People didn’t think in terms of progress a thousand years ago. There actually was progress, but it was so slow as to be unnoticeable.
World Future Review: There are tens of billions of devoutly religious people around the globe. How do you sell the idea of super-intelligence, technological human enhancement, and virtual immortality to a global populace who would have to give up their core religious beliefs to embrace such a future? And would traditional religious beliefs be compatible with a world governed by technology?
Ray Kurzweil: First, I think we should recognize that the major religions emerged in pre-scientific times and we need to update our philosophies based on what we’ve learned in the thousand years or so that we’ve had science. However, such ideas are not necessarily inconsistent with religious beliefs. In fact, the major religions have embraced technology and technological progress and the idea of human beings applying tools to overcome human suffering and extend life here on earth,. The major religions tend to be very pro-life and clearly support medical and scientific progress to expand human longevity. While they may not necessarily talk about radical life extension, [such concepts] are just natural extensions of the idea of human progress which the major religions do endorse. Even the pope has endorsed the idea of using science to overcome disease.
World Future Review: Speaking of e-commerce, you point to a future economic boom based on the exponentially increasing capability of computer power, coupled with decreasing cost, through the fulfillment of Moore's law. Can you tell us a little about the explosion of wealth that will follow the explosion of technology?
Ray Kurzweil: We have economic growth every year. If there’s a very slight downturn one year, we consider that a disaster and call it a recession. But there is economic growth in almost every year and all of that comes from information technology. The information industries grow 18% in constant dollars each year, despite the fact that you can get twice as much each year for the same price, because as price performance reaches a certain level, whole new applications explode. People didn’t buy iPods for $15,000 each15 years ago, which is what they would have cost. Social networks weren’t feasible six or seven years ago. And as new applications become feasible, they suddenly take off. E-books are now taking off because all the enabling factors are in place.
Every industry is gradually transforming into an information industry. Health and medicine is making that transformation now. Most of the economy will be information technology in the 2020s. … This is what’s providing economic growth. The non-information technology industries are shrinking.
World Future Review: I want to talk about something a little different, and that’s the role of creativity in a post-Singularity world. You're the author of some of the first computer programs that compose poetry and music. What place is there in a post-Singularity world for those classic works of art and literature produced by non-enhanced humans—Shakespeare and DaVinci, for example—and how will we redefine creativity and the creative process in general? What will be lost if we give up these processes to software programs?
Also, is there room in the digital future for analog processes? There’s no linear progression when it comes to artistic tools—but there are constellations of widely-varying processes that are different from—but not superior to—the others. Movies didn’t render plays obsolete, for example. What will be lost if we give up these processes in our haste to embrace a fully-immersive technological future?
Ray Kurzweil: Well, first of all, digital technology has already revolutionized the creation of art in every field, including graphic arts and music. Perhaps less so in language—although even there, certainly, research tools and other online tools are certainly helpful. But I was recently at the National Association of Music Merchants show, which I’ve gone to since 1983, and aside from the elaborately-dressed musicians and the cacophony of musical sounds that you hear on the trade show floor, it really looks and reads like a computer conference. I mean, there are some acoustic instruments, but for the most part, the instruments are very sophisticated from a technological perspective and the users are speaking in very sophisticated terms of single-processing and other computer paradigms. Same thing at a graphic arts conference. Graphic artists are using very sophisticated tools. Almost all of commercial music—at least popular music—is done by synthesizers. The digital world is doing a better and better job of emulating specific art forms that have evolved using real-world methods. It’s really just one aspect of virtual reality. I’ve been very involved with that in the musical field.
The ability of the digital world to emulate the real world is advancing and getting more and more subtle. Virtual reality today is cartoon-like, but if you look at Second Life, over the last 18 months, it’s become much more realistic. You can see where it’s headed to being very realistic and three-dimensional and full-immersion. That is the goal of the digital world: to emulate the natural world.
There are still many things that we can’t do in the digital world. You can simulate brush strokes and so on with digital tools, but you can’t yet really achieve the three-dimensional effect of an oil painting. But that’s the direction we’re headed in.

Without the ocean Earth would be a pretty inhospitable place even though we lie within our Sun's Goldilocks Zone. Those of you who live by the ocean can probably figure out why that is the case. You see the ocean is a temperature moderator and a heat transport mechanism that evens out the climate across the planet.
The horror of 298 lives snuffed out by a missile is reverberating around the planet this week after last Thursday's downing of a Malaysian Airlines Boeing 777. How could missile technology meant to shoot down warplanes get used to destroy a civilian aircraft?
I remain skeptical about the economics of industrial technologies for carbon capture. Almost every project started has been heavily subsidized by government. But for the operators without government subsidy there seems to be no return on investment. First of all, all existing industrial carbon capture technologies are expensive to implement.
On a recent driving trip, my wife and I became immersed in the audio version of one of Tom Clancy’s last novels, titled “Threat Vector.” Without giving away too much of the plot, a Chinese super-geek villain has hatched a plan to hack into our most secure networks and blackmail people with their darkest secrets to subversively cause chaos and disruption for the American government.
If you work for the post office these days then you already have an inkling of what the 21st century will do to many jobs. Texting, email, and mobile connectivity have forever altered the way we communicate. How many of us still write letters on paper and mail them?
Some of you who know me personally know that in my formative years I started studying geophysics in university before a physical accident laid me up for more than a year and I in an epiphany changed my major to Islamic Studies and Medieval History. So I was both a science and history nerd all at the same time. Well nothing has changed.
The government in South Korea is organizing its manufacturing sector along with academics and ministries to tackle and develop 3D printing as an economic opportunity. Rather than rely on the hits and misses of free enterprise, the South Korean leadership is directing all interested players within the country to come up with a roadmap that will lead to innovation in manufacturing and the creation of new jobs.
