Nod. 

"There might be anything that bakes at a temperature low enough for your crystals to handle."

"Maybe some of the people with an interest in cooking will accumulate enough certificates to get a cookbook off you and give it a try."

"Adorable. Hopefully they can use enough of the recipes for it to be better than just buying the food."

"They can bet someone it won't be, as insurance!"

Wag. "There you go!"

"I think it'll make people more willing to try things they otherwise wouldn't consider worth it."

"Things more interesting than cookbooks?"

"Yeah. Long research projects and magic experiments and so on. Maybe there's some way to insure against the risk a kid is a liability and then not have to worry they might be and you'll have to kill them if they are."

"...that would be nice, yes, I'm not immediately sure how to do it."

"Me neither. The problem is that long-standing bets create entanglement - isn't that always the problem - and also that it'd be hard to compensate rightly for a risk that's about misfortune, not just debt. - no, wait, that's not a problem, the insurance just has to cover buying the kid out."

"Cover who buying the kid out? Can you make a bet with a child who doesn't exist yet?"

"I've never tried it. Otherwise, you'd cover some elderly human buying the kid out, probably."

"Need a reliable supply of elderly humans."

"Yeah. And other societal things would have to change for buying people out to be enough. But I think they will."

"Don't think we can count on having a reliable supply of elderly humans unless for some reason we wind up harboring a breeding human population who keep real quiet in Limbo once they die. Missing persons reports get more follow-up later on in history."

"Maybe there's some way to transfer the debt to a slow human without them noticing. I don't know how to accomplish that but it could be possible."

"...interesting."

Bounce. "We can ask some court that has dealings with humans, they'll all know that kind of thing."

"Even if they have an interest they haven't necessarily discovered all there is to know."

"Well, if we need to we can experiment ourselves."

"Plenty of time, and all that."

He glances at his brother but his brother has wandered off to mediate a dispute among drunk people.

"Yeah."

"...Am I liable for supplying intoxicants to that dustup over there?"

"Hmmm? No, they made their own choices. Poor choices, apparently. - if I'd been designing the system drugging people would make you accountable for them at least if they weren't informed about it, but I really really really did not design the system."
