"Today’s AIs don’t understand environments; they just pattern-match inside them." Literally what critics have been saying for years now.

🔥 MIT just exposed every top AI model and it’s not pretty. They built a new test called WorldTest to see if AI actually understands the world… and the results are brutal. It doesn’t just check how well a model predicts the next frame or maximizes reward it tests whether it can build an internal model of reality and use it to handle new situations. They built AutumnBench 43 interactive worlds, 129 tasks where AIs must: • Predict hidden parts of the world (masked-frame prediction) • Plan sequences of actions to reach a goal • Detect when the environment’s rules suddenly change Then they tested 517 humans vs. Claude, Gemini 2.5 Pro, and o3. Humans crushed every model. Even massive compute scaling barely helped. The takeaway is wild.. today’s AIs don’t understand environments; they just pattern-match inside them. They don’t explore strategically, revise beliefs, or run experiments like humans do. WorldTest might be the first benchmark that actually measures understanding, not memorization. The gap it reveals isn’t small it’s the next grand challenge in AI cognition. (Comment “Send” I’ll DM you the paper)

It seems some people are still confused about how autonomous the Optimus bots were at the Tesla event. This clip is from another video Tesla released a while ago. It shows how the bots are controlled remotely using a haptic suit, kind of like puppets. Also, during the event, the operators were speaking through a microphone. None of the bots were talking on their own. In short, all the hand movements and speaking were done remotely, but the walking was autonomous.

As Hurricane Milton nears landfall in Florida and over a million people have been ordered to evacuate, corporate price gouging has begun. There are numerous reports of airlines and hotels suddenly jacking up prices as people need to flee. Thread.

This is a very short video about our very long history using technology to tell stories.

BREAKING: The Supreme Court has just ruled 6-3 that it is legal to criminalize homelessness. The Court sided with an Oregon town that made it illegal to camp in public, overturning a decades long precedent that says criminalizing homelessness is cruel and unusual punishment.
