I'm just taking a stab at it, but maybe he/she is making a joke about how an overwhelming amount of the threads in this forum have to do with "this is harder than that" and that it seems like piano culture (or whatever you would call it) is just heading in the direction that one can only be a "good" pianist if they started playing 10 hours a day at age 2 and had all of the Liszt Etudes memorized by age 5. (Sorry if that example isn't impressive enough, and if you think the Liszt Etudes are laughable at best.)
Or maybe it's not that deep.
(Sorry for my ranting, but I'm just getting sick of hearing about teenagers killing themselves to master the Rach 3 or some other extremely difficult piece for some competition. In the words of Bartok, "Competitions are for horse, not artist.")
