The Age of Spiritual Machines

When Computers Exceed Human Intelligence

By: Ray Kurzweil

Narrated by: Alan Sklar

Length: 3 hrs and 34 mins

Publisher's summary

The inventor of the most innovative and compelling technology of our era, an international authority on artificial intelligence, and bestselling author of The Singularity is Nearer now offers a framework for envisioning the twenty-first century in The Age of Spiritual Machines—an age in which the marriage of human sensitivity and artificial intelligence fundamentally alters and improves the way we live.

Kurzweil's prophetic blueprint for the future takes us through the advances that inexorably result in computers exceeding the memory capacity and computational ability of the human brain by the year 2020 (with human-level capabilities not far behind); in relationships with automated personalities who will be our teachers, companions, and lovers; and in information fed straight into our brains along direct neural pathways. Optimistic and challenging, thought-provoking and engaging, The Age of Spiritual Machines is the ultimate guide on our road into the next century.

Critic reviews

"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

too bad it's abridged

I loved the subject matter and the prescient predictions, but the backstory behind them was all chopped out of the book. This version, whittled down to the barest bones, could practically be a series of BuzzFeed articles instead. Sklar's performance was exemplary as always.

I liked it but I liked "How to Create a Mind" more

If you’ve listened to books by Ray Kurzweil before, how does this one compare?

If this book were a movie would you go see it?

no

Terribly Pedestrian

What could Ray Kurzweil have done to make this a more enjoyable book for you?

Written parts of it for audiences that already had some familiarity with futurology or transhumanism. There was nothing in this book that I hadn't encountered before, nor anything that couldn't have been explored in a more nuanced or thoughtful way. His endless predictions for what the future holds, did nothing to leave me amazed or inspired. Nothing truly innovative. Vulnerable to the same problem of Henry Ford's 'Faster Horses'.

Any additional comments?

Great starter book for the uninitiated friend with a hopeful outlook on the future.

An optimist future

The author is a few years off on his predictions, otherwise it's quite thought provoking. Definitely worth the three hours to listen

Wow!

This guy's mind is amazing. his predictions that he had written down in this book are coming true. That make one think that the predictions he has made for 2099 may be correct as well....

Fascinating performance, exciting story.

It is pretty amazing, the accuracy with which Kurzweil predicted 15 years ago where we are today technologically. If you factor in a 5 to 10 year delay due to recession and pandemic, his predictions are almost completely accurate. I work in the tech industry and am passionate about it, so it is clear to me that Kurzweil has a gift for seeing how the seeds of technology will grow. The performance could not have been better by Alan Sklar. I hope to hear more from him.

An optimistic map to technological transcendence

In this short, readable book, Kurzweil pitches the idea of the Singularity to mainstream readers. As a software developer with a strong interest in artificial intelligence, evolution, and neuroscience, I think that his claims and their stunning implications are right. At least, in a broad sense. We are not far from a world in which machines will begin to exhibit intelligence approaching -- and, in some areas, surpassing -- the minds of human beings. Though, at first, such systems will require much direct guidance and management from us, they will become ever more autonomous. They will thrive as members of vast, interconnected, evolving software ecosystem, supported by an immense, powerful, and exponentially growing base of computing hardware.

With the rise artificial intelligence, new physical technology will become possible, enabling machines to begin to become part of us. In a few decades (maybe a century), our brains and bodies will probably have the ability to interface directly with computer systems and nanobots that augment them; in a few decades more, our physical human bodies might no longer be necessary, and we will be able to exist solely as software entities, life forms in a reality that can’t be imagined right now.

It’s mind-blowing, paradigm-imploding stuff, but I’ve thought about the same ideas at great length, and I think that Kurzweil’s reasoning is quite clear and sound. Given what we know about the workings of “intelligence” as represented by the human brain, there’s no obvious reason that science won’t be able to map out its essential processes or computer hardware and software to realize something equivalent to them.

If you need proof of the man’s credibility, note that this book was written in 1999, then check out chapter 3, where he makes predictions of how technology will look in 2009 and years beyond. Granted, many of his forecasts are a little too optimistic -- for example, a suit that provides an enjoyable simulation of sex isn’t going to happen by 2020 -- but his mind was definitely headed in the right direction. The coolest bits of "2009" future-gazing describe technologies that, if not here already (iPhone, anyone?), are getting close. Both in terms of physical realization and rapid public embrace.

However, I would criticize Kurzweil for being so breathless in his excitement, he doesn’t give much attention to the dark side of what he foresees. Certain areas of technology may follow an exponential growth track, but human understanding and social systems are another story. What will happen to the people who are left out of the leap forward, or don’t understand it, or are afraid of it? The ones who have no saleable skills in a world of robots? (Note that one of the few predictions for 2009 that Kurzweil gets drastically wrong is his rosy forecast for the global economy.)

Still, this is a very important book for the mainstream and I can tell you that technology and the concepts around it are developing just as Kurzweil said. The decades to come will be some of the most interesting in human history, and quite possibly the next step beyond human history.

The mind is a beautiful thing!!

The future holds many wonderful and scary reveals and nothing is more frightening to me than AI gone wild!
AI can and will be a great ever life changing part of our lives contributing many beneficial shortcuts to a better life.
But....we know there is a dark side....

A very good look to the future of the human mind and the ever more capable machine!

Not a prophet, just a guy that is paying attention

Ray Kurweil's ideas of the future have been very productive in helping individuals know what target to aim towards, when it comes to future planning. One must understand the concepts in this book to handle the business paradigm changes we will face as access to information is coming faster than we can organize it.

Chaos theory and the fate of the Universe

Worth the read from a wild perspective that we quite possibly have surpassed. It's a good beginning approach to Chaos theory as a science.
