Bohr, objectivity, and "our experience": \`A propos Mermin's note on the quantum measurement problem

In a recent note David Mermin attributed the idea that wave function collapse is a physical process to a misunderstanding of probability and the role it plays in quantum mechanics. There are, however, further misconceptions at play, some of which are shared by Mermin himself and more generally by QBists. The main objective of the present comment on his note is to explain why I disagree with his reading of a well-known passage by Niels Bohr, in particular the ambiguity of the first-person plural he perceives in Bohr's reference to "our description of nature" and "our experience."
