As a Magnus fan this saddens me, but his reasons are understandable: you've got one life to live and he doesn't enjoy spending a quarter of it preparing for these grinding, stressful matches. After five consecutive wins, including a crushing win less than a year ago, and 10 years as world #1, by a considerable margin for most of those years (the gap between him and #2 right now is the same as between #2 and #9, and this is the smallest gap it's been in some time), I think he can make a credible case that he has nothing left to prove and trying to get a 2900 rating is more interesting.

On a related note, my suggestion for an updated WCC format:

We should move away from all classical chess. Yes, that's the tradition that's been going for 150 years, but today so many of the biggest events are rapid and blitz (online tour events, Grand Chess Tour Rapid & Blitz events, World Rapid & Blitz Championships, not to mention two of the last three world championship matches being decided in rapid tiebreaks and many of the biggest classical events decided in rapid or blitz tiebreaks). So I believe the "World Chess Champion" should be the person who demonstrates mastery in a blended format of all three, to represent the importance of all three.

The rapid, blitz, and classical portions all have equal weights (18 points)by following in the footsteps of the Grand Chess Tour Rapid and Blitz events where rapid games are worth 2 times as much as blitz. I suggest 6 classical games, worth 3 points each (1.5 for a draw); 9 rapid games, worth 2 points each (1 for a draw); and 18 blitz games, worth the traditional 1 point each (0.5 for a draw), with the cumulative score determining the winner.
