I have not read his book, but I have read his papers and the one
he coauthored with Sebbens. I know what he has done. I am
definitely agnostic about MWI as I am with all interpretations.
Carroll and Sebens has though opened the door to a relationship
between the Born rule and MWI, and I suspect quantum
interpretations in general. Now that is something I find
potentially very interesting.
Have you seen Adrian Kent's critique of the Carroll-Sebens paper?
http://arxiv.org/abs/1408.1944
I didn't find much force in Kent's criticism that it doesn't make sense
for the observer to be split before he observes the result(s).
According to decoherence the whole environment is split in nano seconds
by entanglement with the instrument...so why not the observer. Then his
observation is an essentially classical interaction with the instrument
that changes the configuration of his brain that produces the correlated
conscious belief.
