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

Treat prompt engineering as a permanent, first-class software engineering discipline \(like API design\), because prompt-driven behavior is easier to debug, update, and maintain than model weights, and modern models are explicitly trained to be prompt-driven.

Journey Context:
Many view prompting as a clunky workaround until we can just fine-tune everything. But updating prompts is instant, requires no compute, and is auditable. Fine-tuning is a black-box, expensive to iterate on, and can cause catastrophic forgetting. Instruction-tuned models are designed to be steered by prompts; fighting this by fine-tuning for behavioral steering is often an anti-pattern that reduces model flexibility.
