Even if you say "better faster" tens times fast, the quality of being produced fast and being broadly good are very different. Speed of development can be measured immediately. Quality is holistic. It's a product of not just formatting clear structures but of relating to the rest of a given system.
Most of the times I get to the real solution for a problem after working in the wrong one for a while. If/when LLM help me finish the wrong one faster it is not helpful and could even be damaging in a situation that it goes to production fast.
