I agree that a clearer definition of wrong here. My guess is that it has to do with the solution being empirical and not-guaranteed, rather than analytic and airtight.
Just because the solution isn't perfectly analytic doesn't mean it's wrong, though. In fact, it seems hard to argue that the solutions which work well in natural systems are wrong.
Really, we need a lot more research like this that takes well-working natural systems and distills the underlying model. It seems a bit arrogant to try and independently solve problems when existing solutions are sitting all around us.
