DeepMind learns chess from scratch, beats the best chess engines within hours of learning.

To add some context: There used to be an era of chess (in the 19th century) called the "Romantic era" of chess. Like Romantic art, it was all about dramatic displays of emotion - or, in chess terms, dramatic sacrifices and tactical combinations. Many of the great classical games that all serious players study date from this area. The idea back then was quality over quantity - the material edge was, well, immaterial if all the extra material of the opponent was sidelined while all your pieces were engaged in a dangerous attack. Most chess players get excited by this style. (Even this year, what has been called the game of the year between grandmasters Ding Liren and Bai Jinshi was this kind of dramatic sacrifical game where the king is chased around the board and mated.)

The problem was that most of these elaborate sacrifices have been proven to be unsound. Modern chess theory, and chess engines especially, will refute almost any dramatic sacrifice or gambit you can imagine. Draws have become incredibly common. Opening theory has improved a ton (even before computer chess), to the point where several chess world championships have invented their own chess variants in order to prevent chess from becoming a stale exercise in memorization.

So when something comes along that combines the flashiness of that bygone era with superhuman playing strength, when something comes along that seemingly breaks all the "rules" that lead to a (perceived) "draw death" or boring style of play, that is exciting.
