A must read for ALL world citizens A must read again!!
Format: Paperback
Fabulous book. Wide ranging, every page full of information that ALL modern citizens should already know or should learn as we go to green technologies and even more dependence on AI and computers. These techs look 'all clean' and 'socially fair' when in fact at every stage (she takes us from design, to engineering to mining, to sales to production of techs) in this 'atlas' of AI we see pollution, inequality, power relationships hidden just beneath the surface. The tip of the AI/computer/green tech iceberg looks all white and clean........the rest (the filth, pollution and inequaity) are all hidden away. Just a tremendous book and not too hard to read. This book should be required reading for all college students, whatever their field!

Embitterment in regard to AI
Format: Kindle
AI is one of the most important innovations in the last decades. But the author of this book claims that the current application of AI is bad. It requires computers that use rare material, the mining of which harms the environment, and it uses inaccurate training data, to list some of the arguments presented in this book. But when considering these drawbacks against AI's blessing (automatic translation, contribution to medical research, etc.), the criticism seems to be not justified. The author blames AI for searching order in an infinitely complex world (in the Conclusion chapter), but she ignores that this is exactly what science does. The book also includes many interesting reviews of the history of science and AI. I enjoyed very much reading these reviews.

Engaging study of the underpinnings of AI
Format: Kindle
This “atlas” maps what is often forgotten when discussing AI: material needs like the extraction of lithium and other minerals from the earth with the destruction of nature that requires and the workers, as well as the epistemological constraints of classification and the false proxies of data. The book is engagingly written and easy to follow while richly sourced. I’ll probably assign at least a couple of chapters to undergrads in our digital culture program. I would have loved an audio book version - but I listened to it using automatic text to speech on my phone and it was surprisingly not awful. This is the first time I’ve done that with a whole book.

A Critical Perspective on the Hype and Reality of AI
Format: Hardcover
Of the many books I have read on AI, having been interested in the topic for 35 years, this is perhaps the most profound. When I read the abstract I thought the goals for the book were going to be almost impossible to achieve. But Kate Crawford has succeeded wonderfully. I find myself referring back to marked sections of the book — and perhaps most importantly questioning some long-held beliefs I have had on the topics. I have shared the book with friends with less time invested in the topic — and they were equally glowing. I hope this finds its way onto the summer reading lists of people with far-flung interests.
