AI seems more like a feature than a product.
While some weather obsessed people will bemoan the difference between various data providers, most people just see the weather and don't know or care how the data gets there.
With the new Siri that's rolling out, I don't think most users would know or care if it was using Gemini, ChatGPT, Claude, or even xAI on the backend. It's mostly trivia when they're all reasonably capable.
