Can we put a lid on this conflation of subjective probability with objective quantum branching please? A deterministic fair coin does not split the world, and neither would a deterministic economic cycle. Or are we taking seriously the possibility that the course of the economy is largely driven by quantum randomness?

EDIT: actually I just noticed that small quantum fluctuations from long ago can result in large differences between branches today. At that point I'm confused about what the anthropics implies we should see, so please excuse my overconfidence above.
