Sam Altman Wants to Rethink Operating Systems. OpenAI Might Build One.

Sam Altman thinks it's time to rethink how operating systems and user interfaces work. The OpenAI CEO tweeted this week that "it feels like a good time to seriously rethink how OSs and UIs are designed."

Coming from the person running the company that kicked off the generative AI boom, that's not idle musing.

The big tech companies are already moving. Microsoft built Copilot directly into Windows 11. Apple announced Apple Intelligence for macOS and iOS 18. Google is pushing Gemini into Android and ChromeOS. But these are AI features bolted onto traditional OS architectures. Altman is talking about rethinking the whole foundation.

Startups are testing what AI-first computing actually looks like. Rabbit's r1 device and Humane's AI Pin both try to replace the app-based interface with intent-based interaction. You say what you want. The device does it. No apps, no menus, no navigation.

Does OpenAI plan to build something here? Altman's tweet doesn't say. But the pieces are there: the models, the developer ecosystem, the user base. Building an OS from scratch is a massive undertaking. So was training GPT-4.

The company best positioned to define AI-first computing isn't Microsoft or Apple. It might be OpenAI.
