Book Review: In Our Own Image
In Our Own Image is a book about the prospects of creating artificial intelligence as well as the cultural, economic, historical, philosophical, and political concerns about it by Greek author and scientist George Zarkadakis. The book considers the problem of AI from the perspectives of human evolution, cybernetics, neuroscience, programming, and computing power.
Zarkadakis begins by briefly speaking of his early years and doctoral research, then spends the rest of the introduction outlining what he will discuss in the rest of the book. The book proper is divided into three parts, each with five or six chapters. The first part covers the evolution of the human brain from the primate brain, especially the most recent 40,000 years. The role of language in accelerating human progress is discussed, as well as the effects of totemic thinking, story-telling, philosophical dualism, and theory of mind. The use of metaphor and narrative to understand the world is examined, along with the inaccuracies inherent in them. The invention, uses, and limitations of the Turing test are explored, as are Asimov’s laws of robotics and the role of AI in fictional stories throughout history.
The second part is about the nature of the mind. The differences in approach between dualism versus monism, rationalism versus empiricism, and materialism versus Platonism are discussed. The thought experiment of the philosophical zombie and the possibility of digital immortality are explained. On the matter of why there appears to be no other intelligent life in the cosmos, Zarkadakis shares an interesting hypothesis: science is an unnatural idea at odds with our cognitive architecture, and an intelligent alien species would be unlikely to widely adopt it. This means that the universe is likely full of Platos, as well as Ancient Greeces, Romes, Indias, Chinas, and Mayas, but is perhaps devoid of Aristotles and societies advanced beyond that of humanity in the early eighteenth century. Daniel Dennett’s explanation of consciousness is overviewed, as well as the contributions of a great number of scientists to the field of cognitive psychology. Finally, the field of cybernetics and its offshoots are examined, showing that the hard problem of consciousness is actually solved with ease. The brain-in-a-vat paradigm of consciousness is shown to be insufficient by applying cybernetic theory.
