Before You Hand Someone a Hammer

A reminder that Generative AI, like any tool, works best when we know what job it is meant to do.

Most of us were not handed tools without instruction.

The first time someone put a hammer in our hands, they probably watched closely. Not because hammers are bad, but because hammers are powerful enough to hurt fingers, dent walls, and turn enthusiasm into repair work.

The same is true in the kitchen. A child is not handed a hot pan, a knife, or a box of ingredients and left alone to figure it out. They are shown what to touch, what not to touch, what to stir, what to watch, and what happens when heat keeps working after the burner is turned off.

We learn tools through guided use.

We learn that not everything goes in the dryer. We learn that a hammer is not the right tool for a screw. We learn that “it worked once” is not the same as “this is what the tool is for.”

The trouble starts when hype teaches us to reach for the closest tool instead of the right one. That is especially tempting when we are still learning to use them.

Large language models are useful tools. They can draft, summarize, brainstorm, compare, explain, translate, and help us think. But the current hype often treats them like a universal hammer. Every problem starts to look like something to pound.

That is where small mistakes can turn into real problems. Not always dramatically. Sometimes the damage is quieter: a bad assumption, a confident wrong answer, a missed edge case, a decision made too quickly because the tool sounded sure.

We do not have to throw away the hammer. The answer is to teach people how to use it.

Start with safe tasks. Show the failure modes. Explain when the tool is useful, when it is risky, and when another tool or another person is needed. Let people practice before the stakes are high.

Before reaching for the tool, ask what the job actually requires.

Good tool use is learned.

We already know this. We learned it in garages, kitchens, laundry rooms, workshops, warehouses, and factory floors.

Generative AI should not be the exception.
