If you look at what OpenAI just did with GPT-5.6, it's not about a chatbot anymore. Native browser control + self-built chip + 150M token context. That's an operating system play, period.
When an AI can see a webpage, click buttons, fill forms, and scrape data autonomously, you've crossed the line from assistant to agent. The browser IS the new OS layer. Microsoft should be more worried than Google right now.
Windows dominance was built on controlling the interface between users and applications. If AI becomes that interface layer, the OS underneath becomes irrelevant. OpenAI doesn't need to build an OS — they just need to make the browser the only thing that matters. And with Playwright baked in, they just did. 🚀
