What happened: Why LLMs can’t make your code simpler

LLMs generate unnecessarily complex code because they lack the Theory, the deep understanding of business context, constraints, and design decisions that exist only in engineers' minds.

Why it matters: Why LLMs can’t make your code simpler

Matters when you review LLM-generated code and wonder why it's verbose or over-engineered despite clear requirements and existing patterns.

Watch out: Why LLMs can’t make your code simpler

No code metric like lines of code or cyclomatic complexity can measure Theory complexity, so LLM training improvements targeting these metrics won't solve the core problem.
