This is a revised and expanded second edition of Why Machines Will Never Rule the World . Its core argument remains the same: that an artificial intelligence (AI) that could equal or exceed human intelligence – sometimes called ‘artificial general intelligence’ (AGI) – is for mathematical reasons impossible. It offers two specific reasons for this claim: Human intelligence is a capability of... Read more

Biography

Jobst Landgrebe is a scientist and entrepreneur with a background in philosophy, mathematics, neuroscience, medicine, and biochemistry. Landgrebe is also the founder of Cognotekt, a German AI company which has since 2013 provided working systems used by companies in areas such as insurance claims management, real estate management, and medical billing. After more than 15 years in the AI industry, he has developed an exceptional understanding of the limits and potential of AI in the future.

Barry Smith is one of the most widely cited contemporary philosophers. He has made influential contributions to the foundations of ontology and data science, especially in the biomedical domain. Most recently, his work has led to the creation of an international standard in the ontology field (ISO/IEC 21838), which is the first example of a piece of philosophy that has been subjected to the ISO standardization process.

Praise for the Second Edition:

“The first edition of Landgrebe’s and Smith's Why Machines Will Never Rule the World was an an excellent and indeed exemplary work of philosophy. But the second, revised and expanded edition is even better: conceptually comprehensive, rigorously argued, formally airtight, and absolutely convincing. So-called ‘artificial intelligence,’ aka AI, is nothing but a myth, because although it's artificial, it cannot, even in principle, be intelligent in the sense in which rational human animals are intelligent; and ‘AI ethics’ is in fact the ‘ethics of human uses of AI.’ This book is profoundly relevant to the present and future condition of humankind.” --Robert Hanna, Editor of Borderless Philosophy

Praise for the First Edition:

"It’s a highly impressive piece of work that makes a new and vital contribution to the literature on AI and AGI. The rigor and depth with which the authors make their case is compelling, and the range of disciplinary and scientific knowledge they draw upon is particularly remarkable and truly novel."
