If you're like most people you haven't really used one since the early 2000s. Dig into the settings on your computer, though, and you'll find them. Apple included a bunch of new screensavers in recent releases, offering 4K videos of cityscapes and nature. They're stunning, but I bet most Mac owners don't realize they're even there. Microsoft, for their part, isn't putting a lot of effort into new screensavers--the ones available in Windows 11 have been there since Windows Vista, which came out in 2007.

Tension fills and permeates the room as millions of eyes are hooked to every single moved performed on the 361 points of the 19x19 grid lines of the board. Their brains hopelessly trying to compute the best of the infinitude of possible positions. Yet the most brilliant mind at it belongs to the man the camera focuses on, the Go 18-time world champion, Lee Sedol. As the clock ticks and the game advances, Lee Sedol delights the public with expressions of surprise and concentration that move by move slowly turn into concern and exhaustion. He rests his head on his palm, rubs his forehead as if looking for a brilliant idea.
