Einstein didn't say that about insanity, but... systems exist and are consistently described by particular equations at particular scales. Sure we can say everything is quantum mechanics, even classical physics can technically be translated as a series of wave functions that explain the same behaviors we observe, if we could measure it... But it's impractical, and some of the concepts we think of as fundamental to certain scales, like nucleons, didn't exist at others, like equations that describe the energy of empty space. So, it's maybe not quite a fallacy to point out that not every concept we find to be useful, like deep learning inference, encapsulate every rule at every scale that we know about down to the electrons, cogently. Because none of our theories do that, and even if they did, we couldn't measure or process all the things needed to check and see if we're even right. So we use models that differ from each other, but that emerge from each other, but only when we cross certain scale thresholds.
