No Deutsch does not agree with this, I know because I've talked
to him about it. In the many worlds interpretation neither
choice nor consciousness nor mind in general have anything to do
with the way the laws of physics work, however in order to
devise a experiment that attempts to prove that Many Worlds
makes better predictions than other interpretations where mind
is important it is obviously necessary to incorporate mind into
the experiment.
Which agrees with my point that the experiment is only designed
to test the Wigner theory that consciousness collapses the
wave-function. Rejecting Wigner's interpretation (which he
dropped later anyway) is not the same as proving MWI.

Isn't that prove wrong any collapse explanations ?
No it just proves wrong theories that say the conscious knowledge of
the quantum computer, which is not erased, collapses the wf. That's
why I say I'd like to see the experimental setup or at least the
theoretical Hamiltonian. Suppose the interference fringes are
observed - then we say OK erasing the which-way, but keeping the
some-way, information is possible. Suppose the interference fringes
aren't observed - then we say it isn't really possible (with the given
experiment anyway) to erase the which-way information and keep the
some-way information. Although the AI doesn't know which-way, the
information is 'out there' just like in the buckyball Young's slit
experiment.

Hi Brent,
Wait... For the the hypothetical quantum computer, what plays the
role of the environment (that is an effectively infinite heat reservoir)
that the IR radiation of the buckyball's couples to such that they (at
some temp) behave classically? Here are a couples of on-line articles:
