God knows. I think we've only seen the beginning of Magnus' potential considering he's only in his early 20's and he's already achieved a superhuman rating and world no.1 title.
has Magnus hit his peak yet

I think it does not matter what his rating his; he will be after all Number 1; nothing better than that!!
he's 22 years old.....when do you think he will be at his "peak" if he's not already
late 20s, 28-30 ....
