Is the Browser the Internet's Entry Point Again, Rather Than the App?

Originally published in Chinese on December 17, 2024. Many AI products now launch as browser extensions, which raises the question of whether the browser is becoming the internet's entry point again. My answer centers on where users get their content and where their data lives. The core of AI services is the source of user data What matters is not whether it is a browser but where users get more content. Cloud data or the model's own data alone is not enough for AI to give users more precise service, so AI needs users to supply more sources of data.
