There are many kinds of noise and the presence of noise is part of
our world with very little needing quantum mechanics to be visible.

The Casimir effect measures quantum noise in a <hard> vacuum
caused by virtual particles.

Then there is a noise of amplification, a noise of sampling, a noise
related to the movement of atoms (heat), Brownian motion, and on and on.

All of these noise sources will remain even if the many-world
theory collapses and dies (low probability).
