Mmh... Here I would say that I agree with P. D. Jones in the sense that
we can agree that the white rabbits problem is almost solved for
Everett QM (by Hartle, Graham, Deutsch and many others (not always in
compatible way though).
... Except that those solution assumed some form of comp, which by UDA,
means that to we must still solve the comp original white rabbit
problem, or abandon comp.
