Chiara Marletto's argument:
- Observers are not subjective entities when described properly.
- Physics has no place for a subjective notion of the observer or differing laws for observers.
- It is suggested that the observation of quantum effects stop them applying in some way - this is not the case (e.g. viruses).
- The QBist postulation of an subjective observer is unnecessary.
- We can make sense of the world in terms of universe laws – it is not necessary to have the observer behave according to different laws.
- Observers can be classified in terms of information theory.
- Constructor theory might unify information theory, thermodynamics, and reduce apparent quantum effects.
