I'm not yet fully convinced. The Deutsch/Wallace exposition is pretty convincing, but when I step back and ask, "Why should there be any probability (in the colloquial sense) at all in deterministic evolution?" The answer seems to defy common sense and I don't know if there is some subtle error.Is Deutsch's explanation fully conclusive?

Incidentally, there is a paper on an attempt at a modal interpretation in which quantum mechanics is really just coarse graining. In this approach, quantum mechanics is not complete, and breaks down at the smallest scales.
