On the digital map of history, when will big tech's USSR moment finally come? Alex Hern

I was born two years before the USSR ceased to exist. The largest country in the world disappeared overnight, replaced by the new largest country in the world, Russia. But the footprint it left took longer to be washed away. I grew up with a duvet cover printed with a world map prominently featuring the ex-nation, reading books and atlases that were published after I was born but before it vanished, and voraciously consuming science fiction that assumed the Soviets would continue to exist far into the future. Randall Munroe, author of the webcomic XKCD, once put together a flow chart to date almost any world map made since the 19th century to within a few years by answering some simple questions.
