I could ask his dad, who was my thesis advisor, but I'm sure he's bothered enough by questions about EdBTW I guess you noticed that the title of the thread is laughable. The Forbes account gave no evidence to support it. Nor did the journalist even state an opinion about the man's state of belief. Nobody but the thread author is pretending to be able to look into a scientist's head and gauge the strength of his belief.
What one can truthfully report (as some try to) is based on the talks people give at major conferences, what their current research emphasis is---the objective signals. With top people (whose casual comments may in part be merely politic) watch what they do.
