That’s Bohr idea. But it means that measurement are no more describe by QM, and 
this introduces a dualism in the the possible theory of mind that you need to 
use. The élégance if the MWI is that QM applies to both the observed and the 
observer, again, like it has to do assuming mechanism.

We still observe the result predicted when accepting the superposed wave going 
through all slit. The fact that we don’t feel the split is entirely explained 
by the wave evolution and the self-duplication thought experiment. Occam razor 
favours the simplest conceptual explanation, or we add add as many “epicycle” 
to favour any interpretation, up to the super determinism, which I take as an 
abandon of rationality…
