But then we're still left without a theory that could explain the behaviour of a single photon without resorting to randomness, correct? > I wonder how comp treats such single photon instances.

My understanding is that it's consistent with the MWI and also with what Russel proposes in his book: everything happens but each observer only perceives one of the outcomes. This seems highly unintuitive to a lot of people, but it seems more reasonable to me than the idea that there is just one Telmo with one personal diary. If there are infinitely many, each one with his own personal diary, the world still looks exactly like it does to this particular instance of me, and we do not have to resort to any randomness magic. It's tempting for me to extend this idea to everyone and not just Telmos, at the risk of sounding a bit new-agey. I don't yet understand how an algorithm could be a random number generator (non-pseudo), but I think Bruno has more to say here.
