"Good dog." Bacon.

The dog is thrilled by the bacon. Once it finishes the piece it was given its eyes are drawn magnetically to the plate.

"Roll over."

It rolls over on its back. It barks happily and lets its tongue hang out of its mouth eyes focused on Mirelótë.

"Good dog." Bit of liver. Can you pause it again now, I don't particularly wish to have it become attached to me and the experiment seems pretty clear.

The dog freezes in the middle of consuming the bit of liver. Of course. The robot with the plate rolls away and disappears through a robot sized door in one of the walls.

The robots are cute.

Thank you, I designed them in the hopes of them looking non-threatening.

They look that way to me; hopefully humans agree.

She heads back to the teleporter to return to reading.

I also programmed them to stay out of sight in the course of their normal activities. I didn't originally plan to use them for deliveries.

While she's outside she'll be able to see her house, the broad structure is complete but the finer details are still in progress. Some of the robots working on the house construction are substantially bigger.

That's nice to see.

She reads, and watches videos, sometimes at the same time; the videos are low resolution and she can read while watching them in her peripheral vision.

It's too early to assume this will be the best idea to be had, especially if we think of a way to be confident of consent to attempt scan-forking, but apparently humans have parks where they line up and go in batches on recreational automated vehicles, and there might be some that are set up in a way that you could teleport out batches.

That sounds promising, though it depends somewhat on how closely these rides are monitored. If large numbers of people are known to have vanished into thin air that might draw attention. 

Yes. That seems likely to be a problem with any solution that doesn't involve finding hermits, though, and those are less efficient...

My original thought was to create some sort of event for which an overnight stay would not be wholly out of the ordinary. The humans are likely to notice my mother's actions sometimes the day after the teleportation and following that they only have a day before their world is destroyed. That may be a point in favor of more geographic distribution actually.

Maybe they have hotels. Although the staff would probably be expected to come home from work...

They at least have a word for hotel.

But a hotel won't have people coming repeatedly into the same location so it's less efficient per teleporter emplacement.

How long does teleportation itself, not reset, take?

There are several durations. Travellers experience an amount of time which is less than the outside time it takes for the teleportation to complete but not zero for long-distances. The time from the teleporter activating at the start and the traveller arriving at the end is roughly the reset time. Any long-distance teleportation requires the cooperation of both ends. What I'm calling the reset time is the outside time duration of the first section of transit.

What I'm wondering is if you could take people off moving trains.

Depending on the size I think I'd be able to convert a train car into a teleporter. It would be a stretch size wise though. I couldn't easily extract some but not all of the passengers on a given train unless it had discrete compartments.

Would you have to attach it to the train or could you set it up by the tracks, waiting for a series of trains and emptying one car from each?

I wouldn't have a way to distinguish between the train car and its contents if the teleporter were built around the tracks. If I knew the train's velocity precisely enough it's possible I could swap out an empty car for a full one but it would be a difficult technical challenge and potentially lead to crashes.

Drat. And it would be visible to onlookers in a station.

It would. I'll think more about this though, there may be some train designs which are well suited to our task. The idea of selectively vanishing some people but not all is also a good way to deflect suspicion.

Reusing one train car might work too, presuming it refills at each station. It just seems slightly more obvious to me.
