They mention in the article that the 14 kb performance cliff applies to compressed size - I believe 32kb is the uncompressed size here

very inaccurate generally, and the markers for eyebrows were just in random places...

to me the point of the poem is that it reminds you that there are 3 classes (30,31,feb) and the rhythm tells how many months are in each class. Remembering 4 booleans for which 4 are the 30 day months is easier than remembering 12 arbitrary integers (unrealistic worst case uncompressed memorisation technique)

this seems more of an argument that a post-scarcity society is impossible than an argument that we are already in one!

It is impossible because basic needs are a moving target.
