Book Reviews of Robot: Mere Machine to Transcendent MindBook Review: Exceeds expectations created by its title Summary: 5 Stars
With high praise from such giants as Sir Arthur C. Clarke and Doctor David Brin on the dust jacket, I asked myself where I, unlettered and relative to them barely conscious, think I'm going trying to write a review. I have a friend who likes to say he never lets ignorance stop him from expressing his opinion on a subject. Guess I remember that one `cause it fits me so well, so here goes.
In his 1950 paper Computing Machinery and Intelligence, Alan Turing grouped the arguments opposing the possibility of machine intelligence into the following nine categories:
1- The Theological Objection - thinking is a function of the soul. Machines have no souls, so cannot think.
2 - The "Heads in the Sand" Objection - Thinking machines cannot be possible because the consequences would be too dreadful.
3 - The Mathematical Objection - Mechanical reasoning has certain provable limitations that human thought may not share.
4 - The Argument from Consciousness - Machines have no inner experiences to give meaning to their utterances, actions, or internal operations.
5 - Arguments from Various Disabilities - Machines will never be kind, moral, joyous, perceptive, original, etc.
6 - Lady Lovelace's Objection - Computers do only what we program them to do.
7 - The Argument from Continuity in the Nervous System - Nerves respond to arbitrarily tiny signal differences, while computers work in fixed-size steps.
8 - The Argument from Informality of Behavior - It is not possible to specify for a machine what to do in every possible circumstance a human might encounter.
9 - The Argument from Extrasensory Perception - Humans sometimes sense remote or future information unavailable to deterministic processes in computers.
Moravec provides current arguments countering each item above, but central to all seems to be this: the principle difference between human and machine is we are conscious. This state, however, is so complex we are unable to explain it. Neither do we understand how or from where it arises in our brains.
The author offers a compelling posit; If as of Robot's publication (1999), the most powerful computers could process a million MIPS (million instructions per second), computers capable of a billion MIPS should be just over the horizon. It will be then, Moravec projects, that the mysterious and exclusively human state we call "consciousness" will be revealed to be not exclusive at all, but merely the capacity to accumulate, process, and interpret sufficient amounts of data in the span of each instant of time - and that when this is achieved, computers will sense the state of their surroundings and thus become "conscious" in the same way we are.
He lays the groundwork for this leap carefully, detailing his personal experiences in robotics and the pace of advances in the field. Arriving at the present day situation, he then takes us step by careful step into the future. It's all completely understandable and reasonable. He's right - know what I'm saying?
Eventually though, his vision of the future exceeds my ability to absorb. I confess to less than a complete understanding of his universe of the future. One thing I did get loud and clear: there were no humans there.
Consider robots an intellectual mutation. These creatures we make will first surpass and then replace us, become us, probably in very much the same way we ourselves replaced the less capable lifeforms we arose from in the distant past. It's not a grim future the author envisions for humanity; it's a comfortable even spiritual retirement. Refuse to accept this, and you'll need to deny Darwin's theories too. Think about it.

Summary of Robot: Mere Machine to Transcendent MindIn this compelling book, Hans Moravec predicts that machines will attain human levels of intelligence by the year 2040, and that by 2050, they will surpass us. But even though Moravec predicts the end of the domination by human beings, his is not a bleak vision. Far from railing against a future in which machines rule the world, Moravec embraces it, taking the startling view that intelligent robots will actually be our evolutionary heirs. "Intelligent machines, which will grow from us, learn our skills, and share our goals and values, can be viewed as children of our minds." And since they are our children, we will want them to outdistance us. In fact, in a bid for immortality, many of our descendants will choose to transform into "ex humans," as they upload themselves into advanced computers. This provocative new book, the highly anticipated follow-up to his bestselling volume Mind Children, charts the trajectory of robotics in breathtaking detail. A must read for artificial intelligence, technology, and computer enthusiasts, Moravec's freewheeling but informed speculations present a future far different than we ever dared imagine. This is science fiction without the fiction--and more mind-bending than anything you ever saw on Star Trek. Moravec, a professor of robotics at Carnegie Mellon University, envisions a not-too-distant future in which robots of superhuman intelligence have picked up the evolutionary baton from their human creators and headed out into space to colonize the universe. This isn't anything that a million sci-fi paperbacks haven't already envisioned. The difference lies in Moravec's practical-minded mapping of the technological, economic, and social steps that could lead to that vision. Starting with the modest accomplishments of contemporary robotics research, he projects a likely course for the next 40 years of robot development, predicting the rise of superintelligent, creative, emotionally complex cyberbeings and the end of human labor by the middle of the next century. After Moravec makes this point, his projections start to get really wild: robot corporations will take up residence in outer space with rogue cyborgs; planet-size robots will cruise the solar system looking for smaller bots to assimilate; and eventually every atom in the entire galaxy will be transformed into data-storage space, with a full-scale simulation of human civilization running as a subroutine somewhere. His last chapter, which mingles the latest in avant-garde physics with hints of Borges's most intoxicating metaphysical conceits, is a breathtaking piece of hallucinatory eschatology. Moravec concludes by reminding us that even the wildest long-range predictions about the technological future never turn out to be as unhinged as they should have been. --Julian Dibbell
