just to add to your excellent observation

by writing code by hand - you're the author & editor at the same time.

if you're skilled enough - you quickly get to the desired state vs the llm which while might produce a lot of code - but it likely won't give the end state you desire.

an analogy - Jason Fried gave - producing software by llm's is like bragging you're a photographer by pressing the shutter button on an automatic camera.

while the art of photography - is about producing the single perfect photo - that communicates the photographers intent (what they want the world to see & experience).

likewise in software - what we make should be deliberate.
