Why hasn’t there been a «new» Warren Buffett?

I’m halfway through reading the Snowball, and obviously Warren Buffett has an extreme amount of experience, interest and natural gift for doing what he does. Still I’m wondering how no one has been able to compare to him after all these years. I saw Jeff Bezos asking Warren the same question, where Warren replied with «No one wants to get rich slow», but out of the millions of investors I feel like atleast a few should definitely have been able to get up there especially with all the new knowledge and strategies available on the subject.
