The deep penetration of AI agents in financial payments and biopharmaceuticals, as well as their native integration into browser workflows, signals the preliminary formation of an AI-native economy and ecosystem. However, the market is clearly divided on the leadership position of tech giants. In particular, the debate over whether Google has fallen behind emerging tools in core areas like programming assistance reflects developers\u0026rsquo; skepticism of large companies\u0026rsquo; closed ecosystems and their desire for agile innovation. In the process of AI empowering marketing and political propaganda, how to balance creative efficiency with religious and ethical boundaries has become a focal point of discussion.
