I disagree, I think it is very clear. If things need to be that precise, if a change in
a quantum state destroys our identity then we die about 10^44 times a second;
That's what you can measure about a state. Per Everett's view the state isn't cloned,
it's just a ray in Hilbert space whose projection on macroscopic subspaces changes.
and a consciousness that never changes is not a consciousness.

The real question is about our minds, and despite what some like Roger Penrose say I
think our minds are probably entirely classical.
Except that random events like a K_40 decay could be amplified up to a macroscopic effect
rarely. Certainly our thinking must be mostly deterministic because a lot of randomness
would be evolutionarily bad.
