The 13-year-old Norwegian prodigy drew Kasparov and defeated GM Anatoly Karpov at the same event in 2004, one month before he became the second-youngest GM in history (and still eighth-youngest as of 2021). At any rate, the clear and remarkable point is that before turning 30 years old, Carlsen had already earned a spot at the top, and he has continued to dominate into his 30s. To many, GM Magnus Carlsen is the best to ever play the game, although GMs Garry Kasparov and Bobby Fischer remain in the conversation.
