Homo Deus: notes on Yuval Noah Harrari 2017 book

Advancements in artificial intelligence could bring about a world in which humans are secondary to self-learning algorithms.

That’s one of the big themes in the 2017 book Homo Deus, a followup by historian and popular intellectual Yuval Noah Harrari on his 2014 book Sapiens. Even more than his first, Homo Deus has been criticized for its wide-sweeping generalizations and his science generalizations. Harrari is one of the chief architects of a kind of techno-pessism so I still find his approach helpful to follow.

He’s a great storyteller, and beyond any debunked science, he engages with concepts I found interesting. I’m sharing notes here for myself. The book is worth reading if only to grasp a view on the treacherous waters some fear are coming due to technical advancements.

My environmental impact

Climate catastrophe is sound science.

More slowly than I’d like to admit, I’ve changed behaviors in recent years. A resolution of mine for this year has been to do more. I wanted to capture a small accounting of what I’ve done so far and how I think I can do more.

Most prominently, last fall, we installed a 12-panel solar array on our roof. According to projections from our installer Solar States, this should more than account for our electricity usage.

Because of that installation, we replaced our traditional natural-gas hot water heater with a heat pump variety from A.O. Smith. We intend to turnover our other appliances (stove, clothes dryer and furnace) too, as part of electrification. Despite being a home from the 1890s, transitioning all of our home to electricity which can be primarily served by our solar installation will be an important contribution. I’ve happily encouraged a couple friends to follow this same transition.

Notes from the 2016 book ‘The Rise and Fall of American Growth’ by Robert Gordon

The “special century” between 1870 and 1970 was not an economic transformation to repeat. It was an anomalous period of exceptional change super-powered by the remarkable inventions of the Second Industrial Revolution not to be repeated.

So argues Robert Gordon in his influential, academic and deeply researched 2016 book The Rise and Fall of American Growth. It is one of the better respected contributions to the conversation how quickly will quality of life continue to advance. Technological advances tend to not reverse, so his point is not that we’ll regress but that we’re due for a long period of languishing growth and advancement.

For millennia until the 1750s, there was very modest rates of economic growth. Then the First Industrial Revolution ushered in slightly faster growth, which setup the second, which we most commonly call the Industrial Revolution of the mid-19th century. That spurred the fastest advancement in quality of life in human history. By the 1970s, progress slowed. The third, technological revolution only resulted in a short-lived return to high grow in the decade 1994-2004. That was the lone answer to economist Robert Solow’s famous 1984 quip: “You can see the computer age everywhere but in the productivity statistics.”

In his book, Gordon argues we’re unlikely to repeat the rate of gains of that special century. It’s an interesting addition to the familiar techno-optimist versus techno-pessimist argument. Below I share some of notes from the book. It is dense and thorough, so it’s hardly light reading, but I devoured it. It’s an important addition to the economic literature. I recommend reading it.
