Frameworks aren't just human-serving abstractions - they're structural abstractions that allow for performant code, or even being able to achieve certain behaviours.

Sure, you could write a frontend without something like react, and create a backend without something like django, but the code generated by an LLM will become similarly convoluted and hard to maintain as if a human had written it.

LLM's are still _quite_ bad at writing maintainable code - even for themselves.
