BREAKING: New startup "RentAHuman" allows AI agents to rent humans to perform tasks they cannot physically perform themselves.

Went down the rabbit hole on this one. The answer is actually wild. 5,000 years ago, Sumerian merchants in modern-day Iraq needed a number that's easy to divide. They picked 60. It has 12 divisors (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60). Base-10 only has four. That's 3x as many ways to split something evenly, which matters when you're dividing grain and wages and can't handle repeating decimals. The counting method is the best part. They used their thumb as a pointer on the three bone segments of each finger. Four fingers, three segments, that's 12 per hand. Track multiples of 12, on the other hand, and you hit 60. No pen needed. Merchants in parts of Asia still count this way today. The system spread from Sumer to the Babylonians, then eastward to Persia, India, and China, and westward to Egypt and Rome. By 1800 BC, Babylonian students were using base-60 to calculate the square root of 2 to six decimal places on clay tablets. One student's homework from 4,000 years ago, now at Yale, holds the most accurate computation found anywhere in the ancient world. The Greeks adopted it for astronomy, which locked it into navigation, cartography, and eventually clocks in the 14th century. People have tried to kill it. During the French Revolution in 1793, France mandated decimal time: 10 hours per day, 100 minutes per hour, 100 seconds per minute. New clocks, new laws, the whole thing. Lasted 17 months. Workers hated getting one day off every ten days instead of one every seven. They tried again in 1897. Scrapped by 1900. The metric system replaced feet and pounds across most of the world. But 60 minutes in an hour? Untouchable. 60 is just too good at being divided. You can split an hour into halves, thirds, quarters, fifths, sixths, tenths, twelfths, or twentieths and land on a whole number every time. Try that with 100, and you get ugly decimals for thirds, sixths, and most common splits. 5,000 years of civilizations looked at that math and came to the same conclusion: 60 wins.
