further observations
civilization has progressed from granaries to treasuries to libraries. now, a complete backup in magnetic medium is trivial, and analog medium is possible (e.g. https://gitlab.com/ks_found/zwibook).
geometric progression makes sense, as does vesting, so are there any good examples of this combo?
XP progression is one-dimensional, whereas global achievements are fungibly memetic. again, are there any good examples of this combo leading to equipment?
crypto has progressed through the hype cycles of forks, then offerings, then collectibles, but since we can realize registries of collectibles that are collectors themselves, are there any good examples of NPC offerings and forks?
furthermore, if NPCs depend on provision of commoditized capabilities, are there any good examples of NPCs that earn "their keep", i.e. autonomous credit, upon immutable orchestrators of such capabilities?
company DATs are (un)sustainable like company towns, but is there a subsistent model for humanitarian DATs?
