"That's good."

"Oh so very much yes."

He's trembling slightly.

"What share of Earth's population d'you' think would move, if the portals were convenient..."

"Right now? I honestly don't know."

"Couple billion, easily, if you were motivated and did the rollout right and had something appealing on the other side."

She shrugs. "Sounds plausible, yeah, although if you went all out on tempting people away you might accidentally panic the existing governments."

"Yeah, plausibly. You can add screening but that increases the number of personnel - you can keep it slow but lots of parts of Earth really suck -"

"Well, you could treat different parts of the world differently--places without as much military power than the US are less of a problem to panic."

"We don't really want North Korea collapsing in our wake... I don't think..."

"Yeah, anywhere with nukes is a problem. North Korea has nukes, right?"

"Yes."

"So. Problem."

"And, generalizing, figuring out the least destabilizing way to give everyone on Earth freedom of movement is going to take probably a lot of people with a lot of local knowledge to be in communication with most of the important governments, and knowing that nukes are specifically a failure mode might or might not generalize to species without an especially earthlike tech tree - I'd say it's encouraging that even the general trajectory of Abaddon looked like ours but they had the same people - Bar, what percentage of societies with the Internet have nuclear weapons?"

I'm afraid I'm hopeless at arithmetic when the numbers get that large.

"Can I please have written works about two thousand societies that have satellite-based commercial communications which mention whether that society has nuclear weapons?"

You're going to have to narrow it down.

"Got satellite-based commercial communications in the last century?"

Time is a very inconsistent benchmark, here.

"First two thousand such books whose word count is divisible by 179?"

"First"?

Curufin!!!!!!

We're working on immortality. What?

You get to ask Bar three questions and from there get an order-of-magnitude estimate of the size of the multiverse. What are the questions?

I take it she won't answer the question directly?
