What AI is (and isn't), in plumber's terms
If you think the model 'knows' code and specs, it'll burn you. Knowing what it actually is keeps you safe.
The idea
An LLM is pattern prediction, not a database of truth. It's great at drafting, summarizing, and reformatting; it's unreliable on exact codes, model numbers, and the newest facts. Treat it as a sharp apprentice, not the authority.
Do it now
Ask it one thing you already know the answer to (a code or spec). Notice where it's confidently wrong.
You should now have: A gut feel for where AI helps vs. where it bluffs.
Guardrail: AI gives you a draft and a second opinion — never the final word on code, safety, or contracts.
