I'm not sure how Wei Dai would answer this, but this is where it comes from in my theory:

Interference, along with most of the other weird aspects of quantum mechanics is a direct result of the measure of observer moments being complex. If quantum mechanics was done using a real-valued Hilbert space, you simply don't get wavelike interference patterns. So why is the OM measure complex and not positive real (like most people assume). Because it can be - complex measures are more general than real valued ones. A real valued measure would require an explanation. Unfortunately, so does a complex valued one, as measures can be even more general than complex valued - see the concept of spectral measure. I suspect division has an important role in order to get real probabilities as ratios of OM measures, and whilst there are still a number of division algebras that can be deployed as measures, possibly the division has to commutative, which would leave just the complex numbers. Alternatively, perhaps the use of these more general spectral measures give exactly the same result as using a complex-valued measure. It would be interesting to develop alternative QM formulations using modules over division rings rather than vector spaces to see if there would be any physically measurable effect of (say) relaxing the requirement of commutivity of multiplication. Alas, this is well out of my comfort zone, so I'll have to pass the baton on to some other foolhardy individual.
