Roger Penrose’s Fashion,[/PLAIN] Faith and Fantasy in the New Physics of the Universe

"Arguing that string theory has veered away from physical reality by positing six extra hidden dimensions, Penrose cautions that the fashionable nature of a theory can cloud our judgment of its plausibility"

is finally published as i write this. in his section on fashion, Penrose considers string theory as fashion and considers problems with extra dimensions

that extra dimensions in string theory are unstable, and increase functional degrees of freedom. this makes string theory unlikely to be correct on purely theoretical grounds.

specifically for Penrose does not think having 4 large dimensions and 6 compactified dimensions is stable. that somehow the 4 large dimensions can be decoupled from the compactified dimensions, and Penrose does not see any reasons for this.

are there any string theorists counter arguments to Penrose extra-dimensions increase functional degree of freedom as he outlines in this book?
