> My hunch is when it comes time to polish and fine tune all the moving parts, this process will remain much faster to do by hand. It will be faster to update a specific field or line of code and test/iterate than to prompt your way through that process (the last 20% of the work takes 80% of the time)

I think you're mostly right here -- however, I think you've framed prompting as an all-or-nothing (or maybe the OP did, as I only skimmed the article too...). LLMs are great for some things (scaffolding, review, refactoring, etc) but way less efficient at others (tweaking and letting the artist eye shine).

I think the crux is this: you shouldn't be asking an LLM to make these tweaks for you; you should be asking an LLM to build the tools that let you make these tweaks by hand faster or more effectively.

For example, we have probably a hundred tools [0] for quickly making all kinds of changes and tweaks in one of our Steam games, that are of course all done by hand. The tools were built by LLMs based on what would speed up our existing by-hand workflows, and once they're built they're just tools that let our people shine.

1. Do a thing by hand

2. Have LLMs build a tool that makes it easier to do that thing by hand

3. ????

4. An artist with a vision can bring that vision to life faster
