I would hope that a 2002 article from Discover magazine, wouldn’t have such an impact on him, that he would change his mind on whether or not there’s a living God of the universe, who created all that there is or ever will be. But I guess stranger things have happened.
Alan Guth is the man who had an impact on Hawking, not that specific article. I merely linked to that article because it explains Guth in the simplest possible way. Guth is widely know as a brilliant cosmologist rivaling Hawking himself. Hawking hasn't had any new ideas since his work on Black Holes, which dates back to the 60s and 70s. Guth is far more cutting edge these days, which is why Hawking has changed his mind as more facts come to light.
