That's beside my point. You are trading off the LoC for quality of code. You're not onto some big secret here - I've also built complete fullstack web applications with LLMs, complete with ORM data models and payment integrations. With the issue being....the LLMs will often produce the laziest code possible, such as putting the stripe secret directly into the frontend for anyone with two neurons in their brain to see.... or mixing up TS and JS code...or suggesting an outdated library version.... or for the thousandth time not using the auth functions in the backend we already implemented, and instead adding again session authentication in the expressjs handlers...etc etc. etc. We all know how to "knock out" major applications with them. Again you are not sitting on a big secret that the rest of us have yet to find out. "Knocking out" an application with an LLM most of us have done several times over the last few years, most of them not being toy examples like yours. The issue is the quality of the code and the question whether the effort we have to put into controlling the slot machine is worth the effort.
