LLMs can't parse the entire codebase at once, understand it, and then make decisions based on that understanding.

The hard part of programming almost is never how ONE function or ONE class works. It's how they all interact in a much larger picture. You can try to mitigate this, but it's a pretty fundamental concept that software is big and just too large for an LLM context window.

Until that's solved, coding has not been 'solved' by '''AI'''. They're useful for greenfield stuff, but new software was always easier to smash out quickly than working on older code.

Plus, it's not like they're building understanding like a person does regardless, even if the context window was somehow enormous.
