I’m not trying to be pedantic, but your use of the word daemon caught my eye, and being a curious person, I looked up daemon vs. demon. Since you mentioned writing, I figured you’d be interested in the results. In short, most of the time they’re interchangeable alternate spellings, but in mythological or religious contexts, daemons are actually helpful spirits of dead people or lesser deities.

STRONGER THAN YOURS INNIT MATE??

I’m not sure this fits the bill, but I’m blown away by the depth and breadth of available hardware. Not computer hardware (tho that’s amazing, too), but latches, levers, nuts and bolts. I can go down a McMaster-Carr rabbit hole the way most people can go down a Wikipedia rabbit hole. It’s just fascinating to me how many highly engineered, precisely machined, perfect, beautiful solutions exist to specific problems. If there’s ever an apocalypse, I’m seriously going to miss the ability to have brilliant mechanical solutions available at the click of a mouse.
