I agree that there is some 'higher' intelligence that is about knowledge creation; say, mathematical inventions like RSA, or new philosophy, or coming up with interesting mathematical problems. But I only asked what is 'required' of intelligence, and we should admit that the vast majority of people, even among those who have above-average intelligence, do not create new knowledge of the grand sort. Most people acquire knowledge in education and then apply that knowledge in their vocation, and their improvements are optimizations or remixings that we already see AI capable of making.
