If Magnus retired tomorrow, who would dominate next and why?

If Magnus retired tomorrow, the title fight would most likely shift toward a new generation Indian prodigy—especially Praggnanandhaa or Gukesh.
I don't think we will have someone like Magnus that will be able to play 2800 performance chess in classic, rapid and blitz for quite some time.
Gukesh is a great classical player but he has a long way to go until he has that sort of performance in rapid and blitz. Firouzja is a bullet and blitz beast but he has lots of ups and downs in classical.
In a way it will be more fun watching hese youngsters fighting for the top spot.

I agree

But more likely to be Gukesh or Hikaru.
Gukesh: pretty good but needs some work when it comes to the skill level that Magnus has
Hikaru: world number 2 but will more likely retire instead of becoming the next best.

The next dominant player certainly won't be a veteran player like Hikaru or Fabi. Maybe one of the youngsters.
It is also possible that no dominant player will emerge for a long time. It's a pretty common situation in chess history. Players who dominate for a decade or more are rare.

I hadn’t thought about that
I personally think that some Indian superstar would prevail, but let me know your thoughts.
