The author ofHomo Deus considers the future of information networks. His international bestseller laying out ideas on human destiny is a hard act to follow, but Harari manages. The first part examines past information networks, leading with the intriguing declaration that “most information isnot an attempt to represent reality.…What information does is to create new realities by tying together disparate things.” What that means is that “errors, lies, fantasies, and fictions are information, too.” Information is often wrong, and more information does not necessarily improve matters, so it’s essential that institutions contain self-correcting mechanisms. Our Constitution receives high marks for allowing amendments; holy books considered infallible, like the Bible and Quran, create problems and “hold important lessons for the attempt to create infallible AIs.” The second part deals with governments whose information networks maintain a balance between truth and order, arguing that just as sacrificing truth for the sake of order comes with a cost, so does sacrificing order for truth. Modern technology enabled large-scale democracy as well as large-scale authoritarianism and totalitarianism. Harari deplores the conception that democracies operate through majority rule. In fact, he argues, democracies guarantee everyone liberties that even the majority cannot take away. This is a sophisticated concept that current events suggest is not universally accepted, and recent advances in artificial intelligence may be an additional destabilizing force. Harari warns that modern societies controlled by carbon-based life forms (us) must deal with inorganic, silicon-based networks (AI) that, unlike the printing press, the radio, and other inventions, can make decisions and create ideas by themselves. AI’s ability to gather massive amounts of information and engage in total surveillance “will not necessarily be either bad or good. All we know for sure is that it will be alien and it will be fallible.” Confronting the avalanche of books on the prospects of AI, readers would do well to begin with this one.
