The Age of Spiritual Machines: When Computers Exceed Human Intelligence Paperback – January 1, 2000
Purchase options and add-ons
“Kurzweil offers a thought-provoking analysis of human and artificial intelligence and a unique look at a future in which the capabilities of the computer and the species that invented it grow ever closer.”—BILL GATES
Imagine a world where the difference between man and machine blurs, where the line between humanity and technology fades, and where the soul and the silicon chip unite. This is not science fiction. This is the twenty-first century according to Ray Kurzweil, the“restless genius” (The Wall Street Journal), “ultimate thinking machine” (Forbes), and inventor of the most innovative and compelling technology of our era. In his inspired hands, life in the new millennium no longer seems daunting. Instead, it promises to be an age in which the marriage of human sensitivity and artificial intelligence fundamentally alters and improves the way we live.
More than just a list of predictions, Kurzweil’s prophetic blueprint for the future guides us through the inexorable advances that will result in:
• Computers exceeding the memory capacity and computational ability of the human brain (with human-level capabilities not far behind)
• Relationships with automated personalities who will be our teachers, companions, and lovers
• Information fed straight into our brains along direct neural pathways
Eventually, the distinction between humans and computers will have become sufficiently blurred that when the machines claim to be conscious, we will believe them.

Editorial Reviews
Amazon.com Review
The Age of Spiritual Machines is compelling and accessible, and not necessarily best read from front to back--it's less heavily historical if you jump around (Kurzweil encourages this). Much of the content of the book lays the groundwork to justify Kurzweil's timeline, providing an engaging primer on the philosophical and technological ideas behind the study of consciousness. Instead of being a gee-whiz futurist manifesto, Spiritual Machines reads like a history of the future, without too much science fiction dystopianism. Instead, Kurzweil shows us the logical outgrowths of current trends, with all their attendant possibilities. This is the book we'll turn to when our computers first say "hello." --Therese Littleton
Review
“From the arrowhead to the jackhammer, toolmakers like Kurzweil have changed the world we live in. . . . This is a book for anyone who likes to think about where current trends are taking us.”—Christian Science Monitor
“Tantalizing—sometimes terrifying. . . . a welcome challenge to beliefs we hold dear.”—Boston Globe
“Kurzweil’s broad outlook and fresh approach make his optimism hard to resist.”—Kirkus Reviews
“This is a book for computer enthusiasts, science fiction writers in search of cutting-edge themes and anyone who wonders where human technology is going next.”—The New York Times

On the misses: he assumed that there would be continuing value to intellectual property, which now appears to be wrong. That particular miss mars some of his other guesses based on that assumption, particularly ones about structuring future economies on the continuing value of intellectual property. (Also, for the computer science types, he also seems to have missed on guesses about genetic algorithms being a key component of AI; that does not seem to have panned out, or, at least, not up to this point.)
The spoiler is that he predicted the end of humanity at the hands of our AI progeny. Let's strongly hope that he got that one wrong, too.
It's not a great pleasure to read this book. Ray Kurzweil is good at writing prose, but his technique of a conversation with an imaginary "Molly" over the decades of the 21st century isn't one that I liked. These imagined conversations make up a fair percentage of the page count (roughly 65 pages of the total 260 pages in the main body of the book, which is over 20%), and I personally found those wearying to wade through.
His timeline in the appendix is excellent, and it is worth skipping to it first, before tackling the text.
I think that this is an important book that everyone should be familiar with, particularly the dire end of MOSHs (Mostly Original Substrate Humans.) We can always hope that we escape that fate!
One area where the book may have been less accurate is that Kurzweil's idea of AI being one computer or a group of computers that has human-like intelligence or superintelligence appears to have been displaced by networking of people, universities, corporations, and government departments (social media and the Cloud). The Cloud would seem to be more or less something like the Singularity he predicts. A good summary of Kurzweil's and AI researcher ideas can be seen in the documentary film "Transcendent Man".
Two other recent topics are worth noting: energy and public health. While there may be some exploration of energy sources for large-scale AI in his other books and in the film, this title does not explain how much solar energy, nuclear reactors, or hydropower would be required for global scale AI networks. If the energy system is not sustainable the AI dream would be quite limited. On public health, specifically disease outbreaks, it is now clear in 2020 that highly infectious diseases like the coronavirus are a challenge that government can respond better to when government uses internet technology, databases, Cloud computing, and "AI", not to mention high-tech manufacturing.
The internet pioneers were optimists about technology's future. Ultimately, we invented and developed modern technology to improve the quality of life. Today, as technology has grown more powerful our choices about how to use technology are more consequential. The knowledge and experience of our leaders and the fairness and decency of leaders overseas will be tested severely by this newly found power.
As far as hardware is concerned, the author insists that Moore's law, according to which computing power at a given cost doubles every 18 months, will continue unabated. Current computer technology will hit fundamental physical constrains in about 10 years, but the author insists that intelligence will find a way to grow explosively without slowing down because of mere physics. He describes several potential avenues through which computer power can increase. The most intriguing one is the possibility of building quantum computers. According to theory these can have immense computing power, because quantum phenomena allow for a huge number of calculations to be done in parallel. Nature does never give something for nothing, and, for my taste, quantum computers come too close to the edge - but who knows?
More interesting is the question of software. When I was a student I was taught that hardware power is not very significant for defining the reach of computers, because algorithmic complexity almost always grows exponentially when related to the size of the problem to be solved. So fundamental advances will come from better algorithms, not from increased hardware power. The current state of affairs seems to agree with this view. After all, word processing 20 years ago using an Apple II is not fundamentally different from word processing today using computers a thousand times more powerful. Algorithmic design is a very costly process that few humans can do well, and this fact, it seems, would necessarily frustrate the rapid increase in machine intelligence. The author produces two solutions: One, to dissect a human brain and copy its "algorithm". To me this sounds rather similar to Da Vinci's idea of dissecting birds in order to build a flying machine. The second solution refers to methods where the algorithm builds itself, i.e. learns how to work. Two methodologies are mentioned here, genetic algorithms and neural nets. Many examples are given about the successful use of these to solve surprisingly difficult problems. These are powerful ideas. Certainly if we come to a point where an intelligent machine can design and maybe build an even more intelligent machine, then indeed we have the ingredients for a runaway explosion of intelligence.
The author paints a rather scary near future. First we use machines to broaden our own minds, but we also build independent machines that become more and more powerful. The war between conscious machines and humans never happens, because it is won by the machines before it even starts: Human minds migrate into machines and lead a fruitful life within the more expansive means that this new medium offers. A few biological humans remain at a much lower level of intelligence, and presumably wilt away without remorse or bitterness. The next level of evolution is achieved by beings that are unimaginably more intelligent than we are now. At this stage it is not meaningful to talk about machines, they are just our offspring living in bodies that are not DNA based. In fact these immortal beings include persons originally born as humans, including, it is stated, Microsoft's Bill Gates. Again, all of this will happen in the next 100 years.
Now, what is wrong in this picture, apart from the idea of having Bill Gates around for all eternity?
For starters, for this vision to work the whole world should be like California, which it is not. On most places of this planet misery rather than intelligence rules. The book was written before the techno-bubble burst, an event not predicted in the book, and also before the recent power failures in California itself. The earth is in such bad working order that one must wonder if ever intelligence will take hold.
Also, if the explosion of intelligence is a necessary natural phenomenon, something like an unstoppable supernova, then by now the universe should be full of manifestations of intelligence, it should be infused, drenched, saturated by intelligence. Why, entire suns would be cloaked in order to harvest their energy needed for the huge amount of computations going on. (Maybe this explains the mystery of the dark matter, i.e. the fact that most matter in the universe is not visible.) Also, why hasn't this cosmic intelligent fabric reached us? Well, maybe they wanted to leave part of the universe in its natural state, you know like we keep protected nature parks. Our corner of the universe may be just such a place. We do not listen to the noise created by intelligence elsewhere, but maybe this only shows our low level of development.
Now, if we assume that the universe is not really intelligent, this leaves us with three possibilities: First, for some reason there may exist intrinsic limits to the growth of intelligence. This does not seem probable, particularly after reading this book. Second, depressingly, the explosive growth of intelligence may always bring about its demise, the same way that the uncontrolled growth of cancer kills the organism that creates it. This sounds rather plausible if we observe the way humanity manages the world today. The third possibility is that the growth of intelligence reaches a level where it decides to stop, where it understands that the "law of accelerating returns" is not conducive to happiness. So maybe the universe is filled not only by intelligent, but also by wise races, that look after their own small garden without disturbing the rest of creation, and live meaningful, biological, limited lives.
All in all, this is an extremely interesting book to read. I withhold one star, only because I find that the catchy title has little relevance to its content.
