These are my opinions and are ruminations on what might be happening as more and more developers use LLMs and Frameworks to build on the web. In October last year I wrote “will developers care about frameworks in the future?” predicting that LLMs would abstract away framework choice. I was wrong—or at least, wrong about the timeline. The reality is more interesting and more permanent: React isn’t competing with other frameworks anymore. React has become the platform. And if you’re building a new framework, library or browser feature today, you need to understand that you’re not just competing with React—you’re competing against a self-reinforcing feedback loop between LLM training data, system prompts, and developer output that makes displacing React functionally impossible.
