> type "make me a calculator app". get your calculator app in an hour or whatever.

What sort of 'app'? A native program for given OS and arch? A webapp? What sort of calculator: scientific, graphic, or just a very simple children's calculator? Does it have large buttons optimised for touchscreens/mouse? Or do we optimise UX for user who types with a physical keyboard?

Sure, you can boil any software 'idea' down to a single short sentence, provided your idea was so simple that virtually any output satisfies it. And if virtually any output satisfies your 'idea', what was its value in the first place? Was there not already some FOSS that satisfied the same requirements long before AI came on the scene?

I've found from my vibecoding experiments I always end up needing to define the exact idea so tightly that my prompt length almost matches the final code length. I often find myself 'programming' in some sort of light pseudocode and letting the agent fill out the details. Any higher level and it doesn't really capture what I want - not due to LLM limitations but the ability for the AI to not read my mind.
