My point is you can't describe what a wave is by pointing at a point.
When an ocean wave hits a beach it efects more than just one grain of
sand.

No, I don't know what you mean.

"Quasi" means apparently but not really, so if it's semi classical
it's only semi correct.

Well that's not very difficult to figure out!If the universe splits
then everything that can happen does happen so the observer splits
just like everything else, so he only sees one tiny branch of the
multiverse.

I have no idea because that's not what happens.Nothing gets "stuck",
no branch of the multiverse has a unique status.
Then do you suppose that the number of branches corresponds to the
probability?

One Brent Meekersees the coin come up heads, and an identical Brent
Meekersees the coin come uptails. Before the flip and before the split
Brent Meekercan't be certain what he will see the coin do so he must
resort to probability. After the flip I don't know if either Brent
Meeker is "stuck" because I don't know what you mean.
