Humanity is facing an impending moral and ethical revolution. The question is not if we create super-intelligent AI, but when. The world’s most sophisticated computers can already out-remember every biological system. And as with other technological advances such as nuclear fission, a single mishap in the advancement of AI technology could set in motion a chain of events devastating enough to outweigh any possible benefit to humanity.
This is the topic of Life 3.0 by the Swedish-American cosmologist Max Tegmark. The paperback is out this summer and the book deals with the impact – or to be more precise, the range of possible impacts – of the rise of AI, from digitally-enhanced humans to a totalitarian panopticon in which an AI super-intelligence monitors every human action.
The book begins by setting out the likely trajectory of human affairs as AI becomes more and more advanced. If Life 1.0 was characterised by primitive organisms such as bacteria (which evolved its own hardware and software), and Life 2.0 was dominated by humans (who evolve their own hardware but design much of their own software – e.g. they have the ability to learn), Life 3.0 will feature robots that are able to design both their hardware and their software.
AI might thus have the ability to break out of any constraints placed upon it. As Tegmark writes, “If we cede our position as the smartest on the planet we might also cede control”. It’s not so much evil robots we will have to worry about, but rather a form of high intelligence whose goals are misaligned with our own.
To the super-intelligent robots of the future, life will effectively be a game, the purpose of which will be to put every atom to its most effective use. There is no good or evil, only competence; and the machines will be far more competent than we are at every conceivable task.
The argument underpinning Tegmark’s book is similar in many ways to that of Homo Deus by the Israeli writer Yuval Noah Harari. The message isn’t one of despondency; rather, we are encouraged to prepare for the fundamental change that AI is going to bring and deal with the ethical and existential considerations it throws up. As Tegmark phrases it, the looming artificial intelligence explosion “may be the best or the worst thing ever to happen to humanity”.
