Collapse "appears" to instruments as well as people - that's why we can
shared records of experiments and agree on them. I'm not sure what you
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.

The measurement problem is the question of why, or even if, collapse
occurs. Certainly no coherent concept of how and why collapse occurs
has been formulated in a manner which meets with general acceptance.
It appears, as Davies and others explain, the appearance of collapse
is purely subjective, as Everett demonstrates. In this case,
consciousness is necessarily central, as it is consciousness, and only
consciousness, which encounters this appearance of collapse and
change. We know there is an effective collapse, or the appearance of
collapse, because we experience this subjectively. On the other hand,
nothing in the physical world, including the physical body and the
physical brain, can account for this. Whatever consciousness is, it
appears to be the phenomenon at the centre of this process. In
consciousness, change is encountered, the appearance of collapse, and,
it increasingly appears, no where else. My paper Logical Types in
Quantum Mechanics <http://philsci-archive.pitt.edu/archive/00005554/>
explains this in detail.

I suspect we all may.
Wong states that, important as a grand unified theory might be, "... it
is lacking in one important fundamental aspect, viz., the role of
consciousness [which] could in fact be considered the most fundamental
aspect of physics."
How does he know consciousness is fundamental?
Given that conciousness seems all too clearly to be centrally involved
in quantum mechanics,
That isn't clear at all
