The vast majority of websites don't need Next.js or React. Those are only useful if you need dynamic and modular updates within the structure, or state management. We've defaulted to React because of the name recognition and simple intertia. It's not a good framework for websites in general.

I'm not convinced you need React/Next.js even in those cases. Web components work and LLMs are so capable of using them that I find there is increasingly little utility in big frameworks.
