I believe there are various dimensions to vibe coding. If you work with an existing codebase, it is a tool to increase productivity. If you have domain specific knowledge, in this case - patient management system, you can build better systems.

Otherwise, you endup simulating the production. Lot of the non technical folks building products with AI Vibe coding are basically building Product Simulations. It looks like a product, functions like a product but behind the scene, you can poke holes.
