To use an example from a different domain, finance, it is completely fair to be skeptical of models and assume there's huge things they may miss. In that case, we have seen models predict things like "this scenario should only happen once in a billion years" - and then occur a few times on consecutive trading days. "Don't overtrust the model" is practically an object lesson at this point, assuming the 'model' here is actually a model and not a literal restatement of physical laws.
