21 Lessons for the 21st Century

by Yuval Noah Harari

In one tragicomic incident in October 2017, a Palestinian laborer posted to his private Facebook account a picture of himself in his workplace, alongside a bulldozer. Adjacent to the image he wrote “Good morning!” An automatic algorithm made a small error when transliterating the Arabic letters. Instead of ysabechhum (which means “good morning”), the algorithm identified the letters as ydbachhum (which means “hurt them”). Suspecting that the man might be a terrorist intending to use a bulldozer to run people over, Israeli security forces swiftly arrested him. He was released after they realized that the algorithm made a mistake. But the offending Facebook post was nevertheless taken down. You can never be too careful.29 What Palestinians are experiencing today in the West Bank might be just a primitive preview of what billions will eventually experience all over the planet.
