Reasoning models reason well, until they don't

Is that really the best title the authors could come up with?

Up next: "Lawn mowers are good at cutting grass until they aren't"

I think that would be a good title if we’d previously thought lawn mowers had solved generalized grass cutting and assumed that because one worked on my lawn that they could cut hayfields or harvest bamboo (a grass I believe) effectively.

When the news cycle has been "lawnmowers can now do anything, throw away your kitchenaide" its a pretty relevant title.
