I agree with the idea that there is no unique spacetime but quantum
superposition of spacetimes. But I think that also the hypothesis
about observer is too strong and leads to philosophical problems.
Just conscious observations are needed, I think.
Various observations given very limited information about
reality which itself changes in every moment of consciousness. Could
this be sufficiently general to be free of internal contradictions?

Criticizing again the idea of observer (without denying that it is
certainly very useful approximate concept at practical level).
Couldn't communication be basically an observation in which communicators
form larger unit of consciousness?
