Great post. A few choice quotes:

> Often the model isn’t flaky at understanding the task. It’s flaky at expressing itself. You’re blaming the pilot for the landing gear.

> The model is the moat. The harness is the bridge. Burning bridges just means fewer people bother to cross. Treating harnesses as solved, or even inconsequential, is very short-sighted.

> The gap between “cool demo” and “reliable tool” isn’t model magic. It’s careful, rather boring, empirical engineering at the tool boundary.

You’re absolutely right! This isn’t your average engineering advice— it’s like painting the reader a vivid tapestry of the author’s mind.

My personal favorite: That’s not a threat. It’s free R&D.
