Hikaru Nakamura will never surpass God Magnus.
I'd prefer to change "never" to "unlikely to ever". Aging affects people differently and eventually Magnus will not be playing at his current level (or his near-future probably better level). The extent to which Magnus and Hikaru retreat from their currently levels has a chance for Hikaru to retreat less and eventually be better than Magnus. Whether or not a slower retreat can be considered "surpassing" is a matter of definition and can be argued against.
Sorry but Nakamura will be never be better than magnus (Fact) his best times already passed his playing strength has not changed in the last 10 years!! if you look closer at the results. In conclusion, He will be always a top player but no more.
I was not addressing a time period when both are in the top 20, but instead was focusing on when Hikaru and Magnus have aged enough and become weak enough that they have both dropped out of the top 100. It is possible that Hikaru might not decline as much as Magnus and at that point you might see Hikaru at #129 and Magnus at #142 (69 year old Karpov has declined 82 points in the last 20 years and that was from a point already significantly lower than his 1980 rating). In their hay day many people did not expect Nigel Short to surpass Karpov, but now that Short is 55 years old he is 9 points higher than Karpov (and for a while in 2004 he was 30 points higher). Odds favor the 3-years-younger Magnus staying higher than Hikaru but Karpov has already closed the two thirds of the gap he had with Short, so maybe Hikaru can do even better by 2050 (at age 63 versus Magnus' 60).
