I kinda agree that the financial system is intelligent in the problem solving sense but disagree that it is pursuing a particular goal in the sense that institutions and organisations are.
It's more akin to an ecosystem to me. In nature we also have ecosystems organising and reusing resources but I would only ascribe intelligence to living organisms pursuing individual goals with agency.
Haven't thought too hard about the distinction though so happy to be shown a better principle.
The entire financial system is a form of artificial intelligence. We just never framed it that way.
It only shocks humans now because they a) never thought about it - it was in the background b) it’s in your face and you can play with it
