[counterintuitive] Is prompt engineering just a temporary hack that fine-tuning will replace

Treat prompt engineering as a core, permanent software engineering discipline \(like API design\), because model weights are stateless and updating them via fine-tuning destroys the generalization that makes them useful.

Journey Context:
Many developers view prompting as a brittle workaround until models can just be fine-tuned to do exactly what we want. But fine-tuning is a low-bandwidth, high-cost update mechanism that risks catastrophic forgetting. Prompting is a high-bandwidth, stateless interface that allows a single foundation model to serve millions of distinct use cases safely. It is the source code of LLM applications.
