IIRC the weaponized sentient pyramid scheme was weaponized against what, if we’re following the book as a map, is today the crypto economy (Economics 2.0 in the book)

Part of the book also fall together nicely if you realize that IRL Stross is a cat person.

I was going to say - that was the part of the book that felt the least plausible when I first read it, but by god, here we are.
