For context, here's the main quote:
> Contrary to how it may seem when we observe its output, an LM is a system for haphazardly stitching together sequences of linguistic forms it has observed in its vast training data, according to probabilistic information about how they combine, but without any reference to meaning: a stochastic parrot.
I think this metaphor is so strained as to not be useful. I think key here is that the authors say "without any reference to meaning", which is a heavily loaded term, that does definitely apply to parrots, but does not apply when you apply it to immense bodies of text.
Namely that language embeds meaning in language. A sentence being written by a human (as a starting point) is designed to have consistent meaning. While it is possible to write syntactically correct meaningless text, that is not what most of human language has done; the meaning cannot be removed from the text.
This I think is clarifying, from the same paragraph in the text:
> ... the training data never included sharing thoughts with a listener, nor does the machine have the ability to do that.
That's just facially incorrect. The training data is entirely about sharing thoughts with a listener. Else why is the text being written?
I don't accept that it applies to parrots. Certainly not to Congo African Grey parrots.
