Language mimicry is not the same as stuttering. Also, I think there's a lack of conceptual clarity in many cases, where people talk about genetics and environment (the academical treatment: https://plato.stanford.edu/entries/innate-acquired/), which certainly doesn't help the ways in which we come to understand ourselves. Even "brain" is terribly misconceived of in a lot of cases. Popular science is a terrible replacement for the nuance and details present in the actual disciplines where the notions are being sifted from. - We're not those scientists. It doesn't make sense for us to invent our own little theories with superficial and simplistic models. It's much better to simply refer to the theories, all the while withholding any attempts at purporting them to be "the answer", instead waiting until properly qualified people can deliver a satisfactory reply. - In that sense, we should be excited to see what might come of it, instead of being stubborn about clinging to our own understanding of it.
