A.I. wud fund it, of course! just like it has funded fiat for 300 years now, or longer, issuing tokens of allegiance; even if the original A.I. was a collective of people - that's psychopathic intelligence, not based in reality or natural law, just a bunch of psychos making sh!t up, believing they get to control other people!

as far as fiat printing: unlimited amount can be printed on the backend, but on the front end, limits can be imposed on how fast and for what one gets to use those fiat tokens; imagine 90% penalty on early withdrawal of retirement funds - what does it matter if the IOU fund made 10x?
