Ray Kurzweil quotes:

Supercomputers will achieve one human brain capacity by 2010, and personal computers will do so by about 2020.

If we look at the life cycle of technologies, we see an early period of over-enthusiasm, then a 'bust' when disillusionment sets in, followed by the real revolution.

No matter what problem you encounter, whether it's a grand challenge for humanity or a personal problem of your own, there's an idea out there that can overcome it. And you can find that idea.

Death gives meaning to our lives. It gives importance and value to time. Time would become meaningless if there were too much of it.

Our intuition about the future is linear. But the reality of information technology is exponential, and that makes a profound difference. If I take 30 steps linearly, I get to 30. If I take 30 steps exponentially, I get to a billion.

I think we are evolving rapidly into one world culture. It's certainly one world economy. With billions of people online, I think we'll appreciate the wisdom in many different traditions as we learn more about them. People were very isolated and didn't know anything about other religions 100 years ago.

All different forms of human expression, art, science, are going to become expanded, by expanding our intelligence.

Aging is not one process. It's many different things going on that cause us to age. I have a program that at least slows down each of these different processes.

My mission at Google is to develop natural language understanding with a team and in collaboration with other researchers at Google.

Science fiction is the great opportunity to speculate on what could happen. It does give me, as a futurist, scenarios.

Information defines your personality, your memories, your skills.

By the time we get to the 2040s, we'll be able to multiply human intelligence a billionfold. That will be a profound change that's singular in nature. Computers are going to keep getting smaller and smaller. Ultimately, they will go inside our bodies and brains and make us healthier, make us smarter.

Once we have inexpensive energy, we can readily and inexpensively convert the vast amount of dirty and salinated water we have on the planet to usable water.

Even by common wisdom, there seem to be both people and objects in my dream that are outside myself, but clearly they were created in myself and are part of me, they are mental constructs in my own brain.

In 1999, I said that in about a decade we would see technologies such as self-driving cars and mobile phones that could answer your questions, and people criticized these predictions as unrealistic.

Our technology, our machines, is part of our humanity. We created them to extend ourselves, and that is what is unique about human beings.

I'm working on artificial intelligence. Actually, natural language understanding, which is to get computers to understand the meaning of documents.

Biology is a software process. Our bodies are made up of trillions of cells, each governed by this process. You and I are walking around with outdated software running in our bodies, which evolved in a very different era.

A successful person isn't necessarily better than her less successful peers at solving problems; her pattern-recognition facilities have just learned what problems are worth solving.

By 2029, computers will have emotional intelligence and be convincing as people.

As order exponentially increases, time exponentially speeds up.

The telephone is virtual reality in that you can meet with someone as if you are together, at least for the auditory sense.

Mobile phones are misnamed. They should be called gateways to human knowledge.

A lot of movies about artificial intelligence envision that AI's will be very intelligent but missing some key emotional qualities of humans and therefore turn out to be very dangerous.

New technologies can be used for destructive purposes. The answer is to develop rapid-response systems for new dangers like a bioterrorist creating a new biological virus.

By 2009, computers will disappear. Displays will be written directly onto our retinas by devices in our eyeglasses and contact lenses.

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from the sunlight.

Doing real world projects is, I think, the best way to learn and also to engage the world and find out what the world is all about.

Launching a breakthrough idea is like shooting skeet. People's needs change, so you must aim well ahead of the target to hit it.

A lot of movies about artificial intelligence envision that AIs will be very intelligent but missing some key emotional qualities of humans and therefore turn out to be very dangerous.

The Singularity denotes an event that will take place in the material world, the inevitable next step in the evolutionary process that started with biological evolution and has extended through human-directed technological evolution. however, it is precisely in the world of matter and energy that we encounter transcendence, a principal connotation of what people refer to as spirituality.

Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity -- technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.

The past is over; the present is fleeting; we live in the future.

I envision some years from now that the majority of search queries will be answered without you actually asking. It'll just know this is something that you're going to want to see.

The story of evolution unfolds with increasing levels of abstraction.

The evolution of animal behavior does constitute a learning process, but it is learning by the species, not by the individual, and the fruits of this learning process are encoded in DNA.

Emotional intelligence is what humans are good at and that's not a sideshow. That's the cutting edge of human intelligence.

When you talk to a human in 2035, you'll be talking to someone that's a combination of biological and non-biological intelligence.

Life expectancy is a statistical phenomenon. You could still be hit by the proverbial bus tomorrow.

Take death for example. A great deal of our effort goes into avoiding it. We make extraordinary efforts to delay it, and often consider its intrusion a tragic event. Yet we'd find it hard to live without it. Death gives meaning to our lives. It gives importance and value to time. Time would become meaningless if there were too much of it.

As we gradually learn to harness the optimal computing capacity of matter, our intelligence will spread through the universe at (or exceeding) the speed of light, eventually leading to a sublime, universe wide awakening.

Artificial intelligence will reach human levels by around 2029. Follow that out further to, say, 2045, we will have multiplied the intelligence, the human biological machine intelligence of our civilization a billion-fold.

If you write a blog post, you've got something to say; you're not just creating words and synonyms. We'd like the computers to actually pick up on that semantic meaning.

The Blue Brain project expects to have a full human-scale simulation of the cerebral cortex by 2018. I think that's a little optimistic, actually, but I do make the case that by 2029 we will have very detailed models and simulations of all the different brain regions.

What we spend our time on is probably the most important decision we make.

I'm an inventor. I became interested in long-term trends because an invention has to make sense in the world in which it is finished, not the world in which it is started.

I decided to be an inventor when I was five. My parents had given me a few various enrichment toys like erector sets, and for some reason I had the idea that if I put things together just the right way, I could create the intended effect.

[In] 2029, I think, computers will match and exceed human intelligence in the ways we're now superior, like being funny, where we still have an edge.

A Singularitarian is someone who understands the Singularity and has reflected on its meaning for his or her own life.

All of our schools need to bring 'learn from doing' into the mainstream education, not just afternoon.

Although I'm not prepared to move up my prediction of a computer passing the Turing test by 2029, the progress that has been achieved in systems like Watson should give anyone substantial confidence that the advent of Turing-level AI is close at hand. If one were to create a version of Watson that was optimized for the Turing test, it would probably come pretty close.

As you go out to the 2040s, now the bulk of our thinking is out in the cloud. The biological portion of our brain didn't go away but the nonbiological portion will be much more powerful. And it will be uploaded automatically the way we back up everything now that's digital.

Biological evolution is too slow for the human species. Over the next few decades, it's going to be left in the dust.

By 2010 computers will disappear. They'll be so small, they'll be embedded in our clothing, in our environment. Images will be written directly to our retina, providing full-immersion virtual reality, augmented real reality. We'll be interacting with virtual personalities.

By the 2030s, the nonbiological portion of our intelligence will predominate.

By the end of this decade, computers will disappear as distinct physical objects, with displays built in our eyeglasses, and electronics woven in our clothing, providing full-immersion visual virtual reality.

By the time of the Singularity, there won't be a distinction between humans and technology. This is not because humans will have become what we think of as machines today, but rather machines will have progressed to be like humans and beyond. Technology will be the metaphorical opposable thumb that enables our next step in evolution.

Death is a great tragedy"¦a profound loss"¦I don't accept it"¦I think people are kidding themselves when they say they are comfortable with death.

Does God exist? Well, I would say, not yet

Evolution is a process of creating patterns of increasing order....I believe that it's the evolution of patterns that constitutes the ultimate story of our world. Evolution works through indirection: each stage or epoch uses the information-processing methods of the previous epoch to create the next.

Find your passion, learn how to add value to it, and commit to a lifetime of learning.

Humans feel deeply the suffering of their friends and allies and easily discount/dismiss the comparable experience of their enemies.

I consider myself an inventor, entrepreneur, and author.

I do have to pick my priorities. Nobody can do everything.

If we could convert 0.03 percent of the sunlight that falls on the earth into energy, we could meet all of our projected needs for 2030.

Intelligence is: (a) the most complex phenomenon in the Universe; or (b) a profoundly simple process. The answer, of course, is (c) both of the above. It's another one of those great dualities that make life interesting.

Intuition is linear; our imaginations are weak. Even the brightest of us only extrapolate from what we know now; for the most part, we're afraid to really stretch.

Inventing is a lot like surfing: you have to anticipate and catch the wave at just the right moment.

It is doubling now every two years. Doubling every two years means multiplying by 1,000 in 20 years. At that rate we'll meet 100 percent of our energy needs in 20 years.

Machines will follow a path that mirrors the evolution of humans. Ultimately, however, self-aware, self-improving machines will evolve beyond humans' ability to control or even understand them.

My view is that consciousness, the seat of "personalness," is the ultimate reality, and is also scientifically impenetrable. In other words, there is no scientific test one can postulate that would definitively prove its existence in another entity. We assume that other biological human persons, at least those who are at least acting conscious, are indeed conscious. But this too is an assumption, and this shared human consensus breaks down when we go beyond human experience (e.g., the debate on animal consciousness, and by extension animal rights).

Nature, and the natural human condition, generates tremendous suffering. We have the means to overcome that, and we should deploy it.

People talk philosophically, Oh, I don't want to live past 100.' You know, I'd like to hear them say that when they're 99.

Play is just another version of work

So what used to fit in a building now fits in your pocket, what fits in your pocket now will fit inside a blood cell in 25 years.

Sometimes people talk about conflict between humans and machines, and you can see that in a lot of science fiction. But the machines were creating are not some invasion from Mars. We create these tools to expand our own reach.

The ethical debates are like stones in a stream. The water runs around them. You haven't seen any biological technologies held up for one week by any of these debates.

The fate of the universe is a decision yet to be made, one which we will intelligently consider when the time is right.

The key issue as to whether or not a non-biological entity deserves rights really comes down to whether or not it's conscious.... Does it have feelings?

The need to congregate workers in offices will gradually diminish.

The profound aspect of technology is that once secrets are revealed, the magic doesn't disappear.

The purposeful destruction of information is the essence of intelligent work.

The software programs that make our body run ... were evolved in very different times. We'd like to actually change those programs. One little software program, called the fat insulin receptor gene, basically says, 'Hold onto every calorie, because the next hunting season may not work out so well.' That was in the interests of the species tens of thousands of years ago. We'd like to turn that program off.

There are downsides to every technology. Fire kept us warm, but also burned down our villages.

There is one brain organ that is optimised for understanding and articulating logical processes and that is the outer layer of the brain, called the cerebral cortex. Unlike the rest of the brain, this relatively recent evolutionary development is rather flat, only about 0.32 cm (0.12 in) thick and includes a mere 6 million neurons. This elaborately folded organ provides us with what little competence we do possess for understanding what we do and who we do it.

Those with engineering skills will build tomorrow's genius computers. But those with the ability to create knowledge of any kind will be the ones who are best able to extract great value from them. The way to create value in the age of genius machines will be to compile and disseminate knowledge that other people will find useful.

Time would become meaningless if there were too much of it.

To transcend means to "go beyond," but this need not compel us to an ornate dualist view that regards transcendent levels of reality (e.g., the spiritual level) to be not of this world. We can "go beyond" the "ordinary" powers of the material world through the power of patterns. Rather than a materialist, I would prefer to consider myself a "patternist." It's through the emergent powers of the pattern that we transcend.

We appear to be programmed with the idea that there are 'things' outside of our self, and some are conscious, and some are not.

We have the means right now to live long enough to live forever. Existing knowledge can be aggressively applied to dramatically slow down aging processes so we can still be in vital health when the more radical life extending therapies from biotechnology and nanotechnology become available. But most baby boomers won't make it because they are unaware of the accelerating aging process in their bodies and the opportunity to intervene.

We only have to capture 1/10,000th of the solar energy landing on earth to completely satisfy all our energy needs.

We'll be able to have very intelligent, little robots with computers going inside our bloodstream, keeping us healthy from inside, destroying cancer at the level of one cell.

We're democratizing the tools of creativity.

What we found was that rather than being haphazardly arranged or independent pathways, we find that all of the pathways of the brain taken together fit together in a single exceedingly simple structure. They basically look like a cube. They basically run in three perpendicular directions, and in each one of those three directions the pathways are highly parallel to each other and arranged in arrays. So, instead of independent spaghettis, we see that the connectivity of the brain is, in a sense, a single coherent structure.

When I was a student at MIT, we all shared one computer and it took up a whole building. The computer in your cell phone today is a million times cheaper and a thousand times more powerful. What now fits in your pocket 25 years from now will fit into a blood cell and will again be millions of times more cost effective.

With the increasingly important role of intelligent machines in all phases of our lives--military, medical, economic and financial, political--it is odd to keep reading articles with titles such as Whatever Happened to Artificial Intelligence? This is a phenomenon that Turing had predicted: that machine intelligence would become so pervasive, so comfortable, and so well integrated into our information-based economy that people would fail even to notice it.
