"Yeah. Crystals don't get hot enough."

"I did notice that! I wonder why."

"My father has a book. I guess probably you shouldn't read it while he's slow and you can't settle. I can read it to you sometime if you'd like."

"That just cuts him out altogether, huh?"

"Yes."

"You realize that's weird."

"It'd be such a nightmare to discover knowledge if whenever someone you told shared it that created debt."

"Things being a nightmare does not preclude them being baked into the system. - metaphorically."

"This is true. But this particular problem doesn't come up."

"Well, fortunately this means I don't have to plan to plant gifts in the homes of every author and composer I want to refer to in the next million years when their lifetime rolls around."

"Seems like the kind of thing that might change the course of history. Or at least that I wouldn't want to take a chance on."

"They could be subtle gifts. I could hide air filters in their rafters!"

"I guess you could! Is there a problem with their air?"

"You can make air filters that get rid of allergens and airborne germs and stuff."

"Huh. Humans seem like their lives would benefit tremendously from more technology. In ways where - more technology will be nice for faeries but it won't be nearly as transformative."

"Currency's a technology, after a fashion. And if we can get the computers working fast they'll be amazing. I might need to know how exactly the thing where credit for a creative work accrues to the latest step in the sharing chain works... maybe if a computer program picks what you read next...? And does speech to text?"

"I have no idea. It'd be worth checking."

Cam writes this down in his inscrutably English notes.

"I think books whose authors are dead are also fine though this does seem complicated by the fact dead people don't stop existing. Like, you're dead, and it's possible to accumulate debts around you normally."

"I'm dead but I'm also here. Limboites don't get summoned. And most daeva aren't ex-humans."

"Then it's probably safe enough to read dead peoples' books but if we didn't get the books from you I wouldn't want to count on it."

"Most of the good stuff is from people not yet born."

"That's trickier. It might not count but it might count and show up when they become people, or something."

"...I'll hunt around for something by someone who will be born soon somewhere and we can test it carefully?"

"Good idea."
