Creativity without knowledge is stupidity. You can't be creative in a setting your ignorant of, so before you can even apply creativity, you must have good knowledge of the base concern and you craft something nice out of existing concerns and bringing it home here, it's the discussion in question.
So creativity and knowledge goes have in hand, after knowledge comes creativity, so I think we're on the same page and there's nothing to disagree with, well unless for the case of someone who's just interested in advertising his stupidity being creative on subject matters he's not conversant with.
Yes that is right creativity and knowledge go hand in hand. We can not have one without other. To create something worthwhile we need to really understand what we are working working with. Knowledge gives us solid base and creativity adds to it. Without knowledge creative ideas might not make sense or work well. In simple words creativity uses knowledge to come up with new and innovative ideas.
