We are entering the era of "Browser-as-an-API." For the last decade, web automation meant fragile Puppeteer scripts that broke the second a frontend dev changed a random Tailwind class name. Using an LLM to dynamically reason its way through a live DOM state in real-time fixes the brittleness problem completely. But it also means the web is about to get slammed with an astronomical amount of automated traffic. The infrastructure cost shift from the client side to the server side is going to be brutal.
