Join 📚 Hadar's Highlights
A batch of the best highlights from what Hadar's read, .
Between the years 3500 BC and 3000 BC, some unknown Sumerian geniuses invented a system for storing and processing information outside their brains, one that was custom-built to handle large amounts of mathematical data. The Sumerians thereby released their social order from the limitations of the human brain, opening the way for the appearance of cities, kingdoms and empires. The data-processing system invented by the Sumerians is called ‘writing’.

a three-year-old girl dying from malnutrition in first-century China because her father’s crops have failed. Would she say ‘I am dying from malnutrition, but in 2,000 years, people will have plenty to eat and live in big air-conditioned houses, so my suffering is a worthwhile sacrifice’?

The last 500 years have witnessed a phenomenal and unprecedented growth in human power. In the year 1500, there were about 500 million Homo sapiens in the entire world. Today, there are 7 billion.1 The total value of goods and services produced by humankind in the year 1500 is estimated at $250 billion, in today’s dollars.2 Nowadays the value of a year of human production is close to $60 trillion.3 In 1500, humanity consumed about 13 trillion calories of energy per day. Today, we consume 1,500 trillion calories a day.4 (Take a second look at those figures – human population has increased fourteen-fold, production 240-fold, and energy consumption 115-fold.)
