I don't believe it. But then again, I tend to not believe things until there is evidence for them (or, at least, enough evidence to show a likelihood, even if not definitive).
All down to not being able to choose what you believe (again). Maybe once it's published there will be enough evidence to convince me but, until then, I'm not convinced and therefore do not believe it. Very intelligent people can be wrong too, even if they are talking about fields in which they are authorities, so their credentials mean nothing unless they can back up their claims with evidence. Just the same as anything else.
