Minecraft is no stranger to simulations, but it turns out that under the right conditions, the game can beat itself… if given billions of years.
This was discovered by YouTuber RedLogic, who built a custom Minecraft simulation to see if the game could ever beat itself without a player ever joining. Two billion years is a bit too long to watch this play out in real time, of course, so he used a Monte Carlo simulation to “compress billions of ticks into explicitly sampled waiting times, while explicitly tracking rare events and the physical resources that can advance or destroy the chain.”
But it wasn’t just a case of time, either. RedLogic needed a Minecraft seed with the right amount of resources and a naturally occuring ender portal, otherwise the game wouldn’t be able to actually complete itself. So, of course, he ran another simulation to find the perfect world and then set the model loose.
While the game did eventually beat itself, it did so at a glacial pace, with tens of thousands or even million of years between milestones. The endermen didn’t even find the portal to the dragon until 35,510 years into
