I think a serious problem. So my theme here at this conference was basically to support the people who want to use quantum mechanics as the foundation of a science of consciousness. Basically maintaining that, for the reasons I've just said, that's obviously what you ought to do because it automatically accounts for all the classical, quantum and classical aspects of the situation, in a seamless unified way, and it brings consciousness right into the equations in a central way. So this suggests that the presence of the observer in the formalism means that it is the act of observation that collapses the wave function. I.e. that consciousness collapses the wave function.
Minds are still very central.
Consciousness is really central in Everett's theory too, because of the following fact. If you just look at the Schroedinger equation, in many situations you get what you might call branches of the wave function. Or you do a measurement and a light flashes or it doesn't flash depending on what the result is. You don't want to lose the predictions of quantum theory, then you have nothing. It's just like if I had a pond, imagine a pond with a circular wall half way out and some slits in the wall and some branches and some holes in the wall so some branches of the wave function come out of this wall.
