You seem to be asserting the anthropic principal, but in doing so you're assuming that quantum mechanics is required for consciousness. But that's not really an answer to this post -- he explicitly calls that out as a possible answer, but why is QM required for consciousness?

Because since we dont understand consciousness, we cannot assume qm to be irrelevant for it, being the basis of the universe, which were just a part of?

Nothing follows from the assertion that we do not understand consciousness. Nothing at all.

But then the question becomes, why exactly is consciousness manifesting in exactly this way as quantum mechanics? There is no escaping addressing this question somehow.
