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

Invest in robust prompt engineering and evaluation pipelines as a permanent layer of your AI stack, not a stopgap.

Journey Context:
Many developers believe prompt engineering is a 'bug, not a feature' of current models, and future models won't need it. However, prompting is effectively programming the model's behavior at inference time. Fine-tuning is expensive, static, and hard to update. Prompting allows for dynamic, iterative adjustment of behavior, chain-of-thought, and tool use, which remain essential even as models improve.
