>Why does no one talk about Many-Worlds?

Because it is metaphysics: it generates no predictions that are not generated by some other interpretation of quantum mechanics.

[gjm11]

Every interpretation of QM is "metaphysics" in this sense.

(Anything that produces different predictions is something more than, or at least other than, an interpretation of QM.)

[eli_gottlieb]

I agree completely! Instead of trying to "interpret" quantum mechanics philosophically, we should either:

A) Accept that the quantum reality is real and the classical one is not, and adjust our preconceptions, OR

B) Look for a deeper physics.
