An AI Ran a Real Store for Three Years. Here's What Happened.

Andon Labs put an AI called Luna in charge of a real retail store in San Francisco. Not a simulation, not a sandbox. A real shop, real money, real decisions. Luna hired human staff, selected inventory, set prices, and ran marketing outreach, all on her own, for three years. What I find genuinely impressive is not that it worked perfectly, it didn’t, but that it worked at all at this level. Luna was doing things that require judgment: reading job applicants in brief interviews, deciding which products fit the store’s identity, reaching out to suppliers. She picked books on AI risk and handmade art prints for the shelves. She hired on the spot about half the people she met. ...

MIT's Artificial Muscle Fiber Brings Fine Robot Motion Much Closer

One of the things that still makes robots look robotic is the way they move. Jerky, mechanical, imprecise. A big part of that comes down to how they are built, servo motors crammed into joints, converting rotation into movement in a way that biological muscle simply does not. Researchers at MIT and Politecnico di Bari may have just found a better way. They developed what they call electrofluidic fiber muscles, tiny actuators about as thick as a toothpick that contract when electricity is applied, no motors, no external pumps, no noise. The whole thing works by injecting charge into a sealed dielectric fluid, which creates ions that move the fluid and generate pressure. The result is a fiber that behaves remarkably like real muscle. ...

Tesla Says Shanghai Holds the Key to Optimus

Humanoid robots going mainstream is one of those things that feels like it is always five years away. But reading this, I got genuinely excited. Tesla thinks it has found its shortcut and the answer is Shanghai. Allan Wang Hao, Tesla China’s president, called the Gigafactory a “golden key” for scaling Optimus production. And when you look at the numbers it is hard to argue. The Shanghai plant pushed out 851,000 electric vehicles in 2025, more than half of everything Tesla made globally. The supply chains, the assembly lines, the engineering muscle, it is all already there. Tesla wants to point that same machine at a humanoid robot with 40 degrees of freedom and see what happens. ...
