You're mistaken to believe that Many Worlds is in conflict with Occam's
Razor.

If you wish to learn more, you could try reading
http://lesswrong.com/lw/q3/decoherence_is_simple/

Near the beginning it suggests a version of your claim:

The Many-Worlds interpretation of quantum mechanics postulates
that there are vast numbers of other worlds, existing alongside
our own. Occam's Razor says we should not multiply entities
unnecessarily.

The entire rest of the post debunks that apparent conflict. The
concluding paragraph is:

The notion that decoherent worlds are additional entities
penalized by Occam's Razor, is just plain mistaken. It is not
sort-of-right. It is not an argument that is weak but still
valid. It is not a defensible position that could be shored up
with further arguments. It is entirely defective as probability
theory. It is not fixable. It is bad math. 2 + 2 = 3.

That's not what Dennett believes at all. A more careful statement would
be: subjective experience is "real"; AIs (will) have it too; and
"zombies" are a logical contradiction (and thus not physically possible).

Chalmers is an idiot.

No, no, don't bother. I can already imagine your mocking reply. Why
should you believe me, over a guy who has actually published
professional articles?

Nonetheless, it's true.

What great phrases! I love the analogies.

Yes, of course, you're exactly right. That's precisely what I meant to
communicate.

Soul and free will are not equivalent.
Calvinists, for instance, believe in soul but not in free will.
