4.0 sonnet about the improvements made on previous versions when it comes to the programming language I'm learning(react native). And it looks like the progress is solid, but this is only what it is saying, not people's experience Note that the questions was taking into account the hours for a mid-level developer?. What's your experience? And I'd like any developer with some experience to respond, not just react native ones. I know e-commerce is quite predictable so more likely to be subjected to automation, but the improvement also applies to other areas, I can't help but wonder how much can it still improve.
