Prompt engineering is babysitting. You type, tweak, correct, and retype — all day. The future is loop engineering: say what you want once, and it plans, runs, checks, and fixes itself on a loop until the job's done.

The shift

Prompt engineering Loop engineering
You babysit the AI You set it up once
Type, tweak, correct The loop runs itself
A draft you have to fix Finished work

How the loop works

  1. Plan — it writes a plan from one sentence.
  2. Run — specialists work in parallel; research never blocks the build.
  3. Check — a checker tries to break it before you see it.
  4. Refine — it fixes what the checker finds, and loops.

The result: one sentence in, a finished thing out. That's the whole idea.
