I feel like the point of the story was that it was celebrating how spectacular the brain is, by showing how unlikely it would seem, and how incredulous another intelligent creature could be upon hearing of it if it weren't already built into their sense of normal.

It might be that this alternative cosmic sense of "normal" is not a real thing (meat may prove to be more cosmically normal than machine at the end of the day), but the sense of wonder in response to something as ridiculous as a brain, in its capabilities and its design, is a real feeling that the story is appropriately trying to evoke.
