I sincerely hope that isn't your prompt. These boilerplate tasks are easy for an AI. You just can't expect to it to get it right all in one shot. You certainly wouldn't do all that in a single commit or even PR.
if you are going to prompt this over the next 50 hours with 300 different prompts, you might as well build it without using AI. that was the point I was trying to make
15 years ago I made, and even sold, games that I spent less than 50 hours making. But that's with the advantage of starting with a generic template that already held all the game menu structure (achievements, preferences, etc.), and even then the games weren't very good.
If you can make a "production grade … application" (irregardless of language details or anything else) in 50 hours, by hand and without AI assistance, you're an unusual person. Most "agile" places I've been, even a single sprint is longer than that.
