"Lots of things seem like they would be, I'm excited to learn about their state of tech."

"Can't you just check?" 

"I could conjure their stuff but I would not exactly be able to read the instruction manuals."

"True. And they're probably not very high on the priority list." 

"Even if they're about to have their own World War II, I don't know where to start looking for ways to avert it," Cam agrees.

"Let's hope it doesn't come to that." 

"Hear, hear."

"Does 2159 still have wars?" 

"There are no ongoing wars as of my departure from 2159 and haven't been in decades."

"Were there any wars after daeva?" 

"Yes. Fortunately, daeva are people and don't start out super-interested in human partisanship."

"There are billions, though, you said;" 

"Yes, but the options when summoning are to go for an individual one you can identify or to offer a general summons and get the first taker. You can't try to summon specifically people who are really invested in exterminating your Buddhist minority or whatever."

"Oh. That's good." 

"It can still get ugly, but a lot of the reasons people have wars are obviated when they don't have any material scarcity."

"I thought wars were mostly about people hating each other." 

"That features, but it's less likely to seem violently urgent if you're comfortable."

"Ooh, yeah, that makes sense." 

"So daeva didn't instantly bring about world peace but it helped a lot."

"It sounds like demons were a bigger impact than angels or fairies." 

"Not as much as you'd think! For one thing, people are more reluctant to summon demons if they can make do without. We're harder to pay, because you can't pay us in any material objects, and people are often scared of us in ways that make negotiating even harder. It's still done, but not by everybody in their backyard. For another thing, by the early twenty-first century, when daeva became common knowledge, a lot of scarcity was driven by the cost of shipping, and fairies cut that down to almost nothing."

"Why are people more scared of demons than angels or fairies?" 

"Probably the name if nothing else, dearheart." 

"Oh. Right." 

"The name and the being hard to pay. The fact that we're hard to pay plus the fact that summons are voluntary - exacerbated enormously by the fact that it's customary to summon demons without letting us talk for fear we'll convince somebody out of their soul - means that a disproportionate fraction of demons who show up to a random summons are there to have a laugh upsetting some human."
