He certainly has all the chances to dominates chess world, I think Aronian, Kramnik, Naka, etc will have to reshape their style to face 5 hour/40 good moves games.
Can Carlsen hold for a decade or more?
carlsen is basically at his peak right now. he is not going to go above and beyone where he is right now.

I feel that Carlsen still has a long time until he peaks performance and will remain champion for at least 10 years. I know there are players who are strong contenders and a number of future ones but Carlsen is going to go above and beyond what he is at now.
