Yes, it's a different argument but it's also generically
correct. But I do think for the discussions in this list it
doesn't matter all that much whether an initial single branch
will diverge into multiple branches due to effectively
classical dynamics.
Branching due to effectively classical dynamics is a
contradiction in
terms. If it's effectively classical it can't branch.
Counterexample: A perfectly balanced pencil on its one atom wide
tip.
Air turbulence will dominate which way it falls.
But air turbulence is a chaotic phenomenon so quantum fluctuations
will eventually grow exponentially and start to affect the pencil.
This repeated appeal to chaos theory to justify a quantum source of
randomness confuses me.
The chaos is not used to justify the quantum randomness, only to
justify the quasi-classical local amplification of a pure microscopic
quantum uncertainty into macorscopic but not detectable, yet "real"
with the MW theory, superpositions.
There is no chaos in QM. It's a classical limit phenomenon.
Absolutely, like irreversibility.
