Not op, no idea either. Best I can make of it is some sort of surrealist fifth level multi layered reference to several memes at once? The only one I know is the trolley problem one
The grand hilbert hotel is a metaphor about infinity. If a hotel has an infinite number of rooms, it will have enough room for him. If every room is full, they can all still move up by one room number. Infinity means you can always shift everyone up by 1 room number.
The ship of theseus is a philosophical question about whether it's still the same ship after having every board and nail in it replaced over centuries of repairs gradually replacing all of its parts.
Asking if Sisyphus is happy is a reference to a famous Albert Camus (French absurdist philosopher) quote "One must imagine Sisyphus happy"
Well obviously it is a philosophical dilemma, but the dozens of ironic variations created for memes gave it a different purpose as meme template.
Otherwise it would be a lot less well known i would guess, under normal circumstances you encounter this perhaps once or twice during your education unless you actively take an interest in such musings. Due to the memes I probably come across the drawing once per week if not more
I love how you call them memes. These are things philosophers talked about long before the word meme had its modern day meaning, even before it was coined in the first place. But in a way, yes, they are all memes
Sysiphus is cursed to forever till a boulder uphill.
The Hilbert Hotel is a philosophical math idea. It has an infinite number of rooms, all full. If you another person wants a room, everyone with a room moves over one. Room 1 moves into room 2, etc. Room 1 is now empty for the new person, and the hotel again has an infinite number of rooms, all full. Just one larger infinite than before.
The Ship of Theseus is a Greek story from Plutarch's Lives about a ship whose parts get replaced as they wear out. The question is - is it the same ship if it has none of the same parts?
Humor is admittedly subjective, but I enjoyed the random mismatched and subversion of expectations enough for a chuckle. The trolly problem setup and pretty much every other detail being ultimately irrelevant is rather amusing in an absurdist humor (Hitchhikers Guild) or anti-joke (yo' Mama's so fat...
