I suspect Sean Carroll is quoted out of > context, as indeed that is a mistake (a common one).* If there is one theme running through Sean Carroll's new book it's that nothing is classical and everything is Quantum Mechanical, and the deterministic wavefunction of the Multiverse can be thought of as a wavefunction of wavefunctions not of worlds because even the concept of a world is just a human approximation. He suggests our current difficulties in finding a theory that goes beyond General Relativity is that we're trying to find something to stick onto it to make it Quantum Mechanical but nature didn't start classical, it was Quantum Mechanical from day one, if there was a day one and there may not have been.
