The other piece of context that's worth noting is that Carlsen is not as good as he used to be (he's still the best player in the world, but not by as big of a margin as he was 5-10 years ago) and that he seems to getting increasingly exasperated with chess itself. Every GOAT eventually retires in a different type of way (Kasparov, Anand, Karpov, all did it a bit differently) and Carlsen's might be coming up soon.
