Life 3.0
Life 3.0: Being Human in the Age of Artificial Intelligence is a 2017 book by Swedish-American cosmologist Max Tegmark . "Life 3.0" discusses Artificial Intelligence (AI) and its impact on the future of life on Earth and beyond. The book discusses a variety of societal implications, what can be done to maximize the chances of a positive outcome, and potential futures for humanity, technology and combinations thereof. Summary. The book begins by positing a scenario in which AI has exceeded human intelligence and become pervasive in society. Tegmark refers to different stages of human life since its inception : Life 1.0 referring to biological origins, Life 2.0 referring to cultural developments in humanity, and Life 3.0 referring to the technological age of humans. The book focuses on "Life 3.0", and on emerging technology such as artificial general intelligence that may someday, in addition to being able to learn, be able to also redesign its own hardware and internal structure. The first part of the book looks at the origin of intelligence billions of years ago and goes on to project the future development of intelligence. Tegmark considers short-term effects of the development of advanced technology, such as technological  unemployment, AI weapons, and the quest for human-level AGI (Artificial General Intelligence). The book cites examples like Deepmind and OpenAI, self-driving cars, and AI players that can defeat humans in Chess, Jeopardy, and Go. After reviewing current issues in AI, Tegmark then considers a range of possible futures that feature intelligent machines or humans. The fifth chapter describes a number of potential outcomes that could occur, such altered social structures, integration of humans and machines, and both positive and negative scenarios like Friendly AI or an AI apocalypse. Tegmark argues that the risks of AI come not from  malevolence or conscious behavior per se, but rather from the misalignment of the goals of AI with those of humans. Many of the goals of the book align with those of the Future of Life Institute, of which Tegmark is a co-founder. The remaining chapters explore concepts in physics, goals, consciousness and meaning, and investigate what society can do to help create a desirable future for humanity. Reception. One criticism of the book by "Kirkus Reviews" is that some of the scenarios or solutions in the book are a stretch or somewhat prophetic: "Tegmark's solutions to inevitable mass  unemployment are a stretch." AI researcher Stuart J. Russell, writing in "Nature", said: "I am unlikely to disagree strongly with the premise of "Life 3.0". Life, Tegmark argues, may or may not spread through the Universe and 'flourish for billions or trillions of years' because of decisions we make now — a possibility both seductive and overwhelming." Writing in "Science", Haym Hirsh called it "a highly readable book that complements The Second Machine Age's economic perspective on the near-term implications of recent accomplishments in AI and the more detailed analysis of how we might get from where we are  today to AGI and even the superhuman AI in ." "The Telegraph" called it "One of the very best overviews of the arguments around artificial intelligence". The "Christian Science Monitor" said "Although it's probably not his intention, much of what Tegmark writes will quietly terrify his readers." "Publishers Weekly" gave a positive review, but also stated that Tegmark's call for researching how to maintain control over superintelligent machines "sits awkwardly beside his acknowledgment that controlling such godlike entities will be almost impossible." "Library Journal" called it a "must-read" for technologists, but stated the book was not for the  casual reader. The "Wall Street Journal" called it "lucid and engaging"; however, it cautioned readers that the controversial notion that superintelligence could run amok has more credence than it does few years ago, but is still fiercely opposed by many computer scientists. Rather than endorse a specific future, the book invites readers to think about what future they would like to see, and to discuss their thoughts on the Future of Life Website. The "Wall Street Journal" review called this attitude noble but naive, and criticized the referenced Web site for being "chockablock with promo material for the book". The  hardcover edition was on the general "New York Times" Best Seller List for two weeks, and made on the New York Times business bestseller list in September and October 2017. Former President Barack Obama included the book in his "best of 2018" list. Business magnate Elon Musk (who had previously endorsed the thesis that, under some scenarios, advanced AI could jeopardize human survival) recommended Life 3.0 as "worth reading".
