Writing is two things above all: it is a craft, and it is a personal communication. (I suppose some technical writing might be excepted from this.) Writing that claims to be from me to you but is actually from me and my Bot—or even just my Bot—to you is inauthentic and sometimes even deceitful. It involves a person in the reader, but the personhood conveyed through the writing is compromised. This writing involves impersonation as much or more as it involves a real person in the human author. And insofar as writing is a craft, if I were in a Medieval-style guild for writers, I can’t imagine letting an apprentice pose as a master or even a journeyman simply because he had found a way to impersonate one, to produce something that poses as masterful work.
