Digital doomsday: the end of knowledge
“IN MONTH XI, 15th day, Venus in the west disappeared, 3 days in the sky it stayed away. In month XI, 18th day, Venus in the east became visible.”
What’s remarkable about these observations of Venus is that they were made about 3500 years ago, by Babylonian astrologers. We know about them because a clay tablet bearing a record of these ancient observations, called the Venus Tablet of Ammisaduqa, was made 1000 years later and has survived largely intact. Today, it can be viewed at the British Museum in London.
We, of course, have knowledge undreamt of by the Babylonians. We don’t just peek at Venus from afar, we have sent spacecraft there. Our astronomers now observe planets round alien suns and peer across vast chasms of space and time, back to the beginning of the universe itself. Our industrialists are transforming sand and oil into ever smaller and more intricate machines, a form of alchemy more wondrous than anything any alchemist ever dreamed of. Our biologists are tinkering with the very recipes for life itself, gaining powers once attributed to gods.
Yet even as we are acquiring ever more extraordinary knowledge, we are storing it in ever more fragile and ephemeral forms. If our civilisation runs into trouble, like all others before it, how much would survive?
