Probably someone else must've also watched this in the past few hours or days.
I remember the book of https://en.wikipedia.org/wiki/Henry_Darger or https://en.wikipedia.org/wiki/Dwarf_Fortress or Cataclysm DDA .
And weird games as https://en.wikipedia.org/wiki/Nomic .
What’s marvellous about this work is the antithesis of AI and computers, the artist and the process are what’s fascinating about it. Generative map and art programs are a dime a dozen. Those have value in their own way, but it’s different from this. There’s no need to conflate the two, most things do not need or benefit from AI.
