Re "aging well" - here is a post from Mike Hearn dated November 2015: On Block Sizes. One section in that post has aged very well: "Core won’t raise the limit":
There’s a widespread belief in the Bitcoin community that all Bitcoin developers want the block size to rise and all that’s required is enough time for them to reach consensus about the best way to do it. These beliefs probably come from the fact that the community has repeatedly been told that by people involved in development.
Both beliefs are entirely wrong.
In 2015 and early 2016, nobody was publicly against raising the block size limit - the question was only "when" and "how", not "if". Then slowly the narrative changed, for some the 1 MB block size limit seemed to be one of the defining characteristics of Bitcoin.
There were indeed some valid technical arguments against raising the blocksize in 2015, but those were invalidated during 2016 as I see it.
