A startup called Sabi just came out of stealth with a beanie that reads your thoughts. 70,000 to 100,000 miniature EEG sensors woven into the fabric. You put it on like a winter hat and type by imagining the words. Sabi's bet is that if you throw enough sensors at the skull, you don't need to open it. They've already logged 100,000 hours of brain data from 100 volunteers to train a "brain foundation model." First product ships by the end of 2026. A baseball cap version is next. Backed by Vinod Khosla, who also wrote an early check to OpenAI. Khosla: "The biggest and baddest application of BCI is if you can talk to your computer by thinking about it. If you're going to have a billion people use BCI for access to their computers every day, it can't be invasive." The first consumer BCI won't look like a medical device, but instead like something you already own. Media
