A "10% better" tool could make no difference, or it could make the work 100% better. The impact isn't linear.

It's likely probabilistically linear... like speeding on a street with random traffic lights.

Right, I should have put a "necessarily" in there.

It also doesn’t magically make you more money either.

Depends on the definition of better. Above example used this definition implicitly as you can see.

Above example makes no sense since it says ChatGPT is 10% better than Claude at first, then pivots to use it as a 10% total productivity enhancer. Which is it?

Yeah, but that's the sales pitch.
