Indeed, the OP's point seems very focused on programmers enjoying programming. And that's a perfectly laudable goal, but obviously this then means that the goal is programmer enjoyment, satisfaction, etc. If the goal is code that allows the user to benefit while also being correct and secure, then that drastically changes the economics and hence potential solutions of what parts of the work should be done by a LLM agent and what parts of the work should be done by a human agent. Economics is the study of the allocation of scarce resources to satisfy human wants; so what you want from code determines a great deal of how to get there with the greatest benefit and the least cost.
