Collapse "appears" to instruments as well as people - that's why we can

mean by "account for" collapse.  At least one interpretation of QM,
advocated by Peres, Fuchs, and Omnes for example, is that the "collapse"
is purely epistemological.  All that changes is our knowledge or model
of the state and QM merely predicts probabilities for this change.
Such epistemological theories need to be carefully distinguished from
"consciousness causes
collapse" theories.

Right. Epistemological "collapse" is nothing but a change in information that causes us to change our description.
