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

Treat prompt engineering as a permanent, core software engineering discipline; invest in robust prompt versioning, dynamic construction, and evaluation pipelines rather than viewing it as a stopgap.

Journey Context:
Many developers believe that as models get better or fine-tuning gets cheaper, prompt engineering will vanish. In reality, as models become more capable \(e.g., agentic\), the complexity of orchestrating them via prompts increases. Fine-tuning cannot adapt to dynamic runtime contexts, API schemas, or real-time tool definitions. Prompting is the API of cognitive computing—the mechanism by which software interfaces with the model's latent capabilities at runtime.
