Taylor would be a fool to get rid of the gray. Does anyone remember that bit a couple of weeks ago when he showed what he had to do to become "incognito" -- he put on a hat so that no one could see his hair, and then he could go out on the street without people noticing him. That's exactly it -- people notice that hair! And many of the comments from his fans indicate that they like him exactly because he's such an individualist. He'd be a complete idiot to let AI or some stylist talk him out of his current look.
I'm guessing that the article you mentioned is a plant from an AI publicist, and that in reality, he has absolutely no intention of changing. But the whole question has raised a lot of notoriety for him, hasn't it? :)
I think you're exactly right. Remember on Tuesday night, Seacrest floated the possibility of Taylor dying his hair--the audience replied with a LOUD unanimous NOOOO!
And this photo is just stupid:
He looks older with dyed hair than he does with the gray, not to mention ridiculous.
