I think a product should answer a specific need, it cannot be fully defined internally, it is an expression of some need in the environment which makes it a legitimate product. A product with no viability soon ceases to be a product. Generating code is not the same with answering a need, it is orthogonal. Good products have market fit, not necessarily are themselves well written apps.

The vibe-coded demos everyone's tired of are code with no environmental need pulling on them.
