Skild AI unveiled the "Messinator," a robot trained to play football via 140 years of self-play in a virtual World Cup environment.

Researcher yifansu312 explains the motivation: AlphaGo and AlphaStar showed how far self-play can go in digital worlds, and the open question is what happens when you bring self-play into the physical world—where a strategy must not just look good but actually work through real robot bodies. More technical details are promised later; the demo is framed as a tribute to Messi.
