Shrodinger's Cat Paradox: A Possible Solution

[Demystifier]

I am reading "Beyond Einstein" by Kaku and one quote in the book specially caught my attention.

"... the superstring theory provides ... comprehensive way of looking at Schrodinder's cat. Usually, in quantum mechanics, physicists write the Schrodinger wave function of a certain particle. However, the complete quantum mechanical description of the superstring theory requires that we write the Schrodinger wave function of the entire universe... This does not resolve all the philosophical problems associated with Schrodinger's cat; it merely means that the original formulation of the problem ... may be incomplete."

I have published several papers in peer-reviewed journals on the relation between string theory and the measurement problem in QM, so I guess someone could call me an expert for such stuff. Still, the quote above does not make any sense to me.
