Loop engineering is the skill quietly replacing prompt writing in 2026. Here is what it actually is, where it came from, and how to put it to work in your business, even if you have never written a line of code.
For about two years, getting something useful out of an AI meant sitting there and typing. You wrote a prompt, read the answer, typed the next thing, corrected it, tried again. You were holding the tool the entire time.
That era is ending. The people getting the most out of AI right now are not writing better prompts. They are building small systems that do the prompting for them, on a schedule, while they sleep. The AI runs itself in a cycle, checks its own work, remembers what it did, and only comes back to a human when it is stuck or finished.
