Homo Deus: A Brief History of Tomorrow

“Of course, by 2033 many new professions are likely to appear, for example, virtual-world designers. But such professions will probably require much more creativity and flexibility than current run-of-the-mill jobs, and it is unclear whether forty-year-old cashiers or insurance agents will be able to reinvent themselves as virtual-world designers (try to imagine a virtual world created by an insurance agent!). And even if they do so, the pace of progress is such that within another decade they might have to reinvent themselves yet again. After all, algorithms might well outperform humans in designing virtual worlds too. The crucial problem isn’t creating new jobs. The crucial problem is creating new jobs that humans perform better than algorithms.20”

“…Suppose you have two free hours a week, and are uncertain whether to use them playing chess or tennis. A good friend might ask: ‘What does your heart tell you?’ ‘Well,’ you answer, ‘as far as my heart is concerned, it’s obvious tennis is better. It’s also better for my cholesterol level and blood pressure. But my fMRI scans indicate I should strengthen my left pre-frontal cortex. In my family dementia is quite common, and my uncle had it at a very early age. The latest studies indicate that a weekly game of chess can help delay its onset.”

“From a Dataist perspective, we may interpret the entire human species as a single data-processing system, with individual humans serving as its chips. If so, we can also understand the whole of history as a process of improving the efficiency of this system through four basic methods:”

“Capitalism did not defeat communism because capitalism was more ethical, because individual liberties are sacred or because God was angry with the heathen communists. Rather, capitalism won the Cold War because distributed data processing works better than centralised data processing, at least in periods of accelerating technological change. The central committee of the Communist Party just could not deal with the rapidly changing world of the late twentieth century. When all data is accumulated in one secret bunker, and all important decisions are taken by a group of elderly apparatchiks, they can produce nuclear bombs by the cartload, but not an Apple or a Wikipedia.”

“Doubts about the existence of free will and individuals are nothing new, of course. More than 2,000 years ago thinkers in India, China and Greece argued that ‘the individual self is an illusion’. Yet such doubts don’t really change history much unless they have a practical impact on economics, politics and day-to-day life. Humans are masters of cognitive dissonance, and we allow ourselves to believe one thing in the laboratory and an altogether different thing in the courthouse or in parliament. Just as Christianity didn’t disappear the day Darwin published On the Origin of Species, so liberalism won’t vanish just because scientists have reached the conclusion that there are no free individuals.”

“…Meanwhile in the USA paranoid Republicans have accused Barack Obama of being a ruthless despot hatching conspiracies to destroy the foundations of American society – yet in eight years of his presidency he barely managed to pass a minor health-care reform.”
