An AI has learned to play Minecraft after watching YouTube videos of people playing the game for 70,000 hours.

If movies have taught us anything, it's that we're inevitably hurtling toward a future where robots will become so advanced that they'll rise up against their creators and wage war on humankind. And it looks like we're one step closer to Terminator becoming a true story with an AI that's learned how to play Minecraft.

OpenAI has shared its success with a tweet showing the clever AI in action, chopping down trees to make wooden objects, mining for stone after whipping up a pickaxe, and discovering diamonds deep in a cave. "With fine-tuning, our model can learn to craft diamond tools, a task that usually takes proficient humans over 20 minutes," says OpenAI in a blog post (opens in new tab).

Okay, so this artificial intelligence clearly has some skills, but how did they get so good at the blocky builder? Well, by watching over 70,000 hours of people playing the game online.

We trained a neural network to competently play Minecraft by pre-training on a large unlabeled video dataset of human Minecraft play and a small amount of labeled contractor data. https://t.co/a2pyBqvLvg pic.twitter.com/XbqtwQSTwUJune 23, 2022

Impressively, the company says that the AI can also perform other tasks it's learned from observing human players' actions, including swimming, hunting, and cooking. It's also perfected the art of 'pillar jumping', a popular technique that involves jumping and placing a block beneath you to fashion a makeshift pillar that allows you to reach higher places. 

Although we've previously seen machines master games like Chess and Go, an AI able to play an open-ended game like Minecraft as well as (or better
