Of course. But this is taken into account in the theoretical reasoning where we suppose

We cannot know our "right level", so we are not trying to build an artificial brain. The
measure problem comes from the fact that, whatever the level is, the physics has to be
given by a measure on computations. That is enough to already derive the logic of the
observable, and that a step toward solving the measure problem, although some other
possible manner might exist.
But I think that implies that consciousness (at least human like consciousness) cannot
exist without the physics; that materialism is not optional.
