The tool is not the moat

I built a tool that took a finished design and cut it into pieces ready to ship. Then models got good enough to do the same thing from a single sentence.

If the value is in a single transformation, a model will eat it. If the value is in the system around it, it won’t.

What a model can’t do alone is know your business: who approves what, where the data lives, what "done" means here. That context is the moat. The tool is just the last step.

One rule

Build the system around the tool, not the tool.
