I can get it to iterate and improve. So I believe it is possible with a better model and better prompts.
For writing "business logic", AI is already capable enough. AI is cranking out satisfactory code for the garbage requirements that coders have to deal with in the corporate sphere.
For elegant art that coding as a hobby demands, the AI doesn't satisfy. It isn't satisfying to use, and the results are not satisfying to read. That said, I made a bunch of shitty little games with AI.
What actually impressed me is that Claude is clearly a coding model, but I squeeze stuff out of it that isn't code at all.
Like a minimal table-top RPG rules set inspired by original AD&D (1st edition) and mashed up with the aesthetics of 24XX by Jason Tocci.
I even used Claude to run some solo playtests, forced to read the rules and play both sides of a short adventure. Then it gives me feedback about what it found confusing, what it had to make up, what worked, etc. Certainly it gets things wrong a LOT. Often trying to slip into 5e rules instead of the rules in the new system or the AD&D 1e rules that are my baseline.
