It feels like the cohort GM player pool is mentally cooked against Magnus. Youngsters like Lazavik during the Speed Chess Championship or Sindarov in Freestyle were the most recent convincing wins against Magnus, but the historical mental edge that Magnus comes into each game after beating the brakes out of everyone is hard to overcome. Magnus' time will come! But not today.
I'd go further to say I think this is true in many things. For instance if you're into wrestling, you know the name of Alexander Karelin [1] who ended his career with a record of 887 wins and 2 losses (both losses by a single point and both highly controversial). He was winning olympic gold, repeatedly, not only without a single defeat but without his opponents even scoring a single point against him. His ears tell the story - 889 world class matches, and he doesn't even have cauliflower ear.
