“I thought you said you could just read his brain electronically,” protested Ford.

“Oh yes,” said Frankie, “but we’d have to get it out first. It’s got to be prepared.” “Treated,” said Benjy. “Diced.”

“It could always be replaced,” said Benjy reasonably, “if you think it’s important.”

“Yes, an electronic brain,” said Frankie, “a simple one would suffice.”

“A simple one!” wailed Arthur.

“Yeah,” said Zaphod with a sudden evil grin, “you’d just have to program it to say What? and I don’t understand and Where’s the tea? Who’d know the difference?”

“I’d notice the difference,” said Arthur.

“No, you wouldn’t,” said Frankie mouse, “you’d be programmed not to.”

Well, sleep and cruise ships don't destroy and copy your body. Teleportation would be equivalent to being killed the way I see it, until we get a better understanding of conscience at least.

Your body slowly replaces itself. I'm reasonably sure that when you die you have replaced almost all of its atoms at least once.

I've been using the same broom for 20 years! Never needed a new one and I'd never think of getting a new one. Of course I've replaced the handle twice and the brush four or five times.

Eventually, the constituent atoms themselves perform a complete cycle (at the slowest rates) every ~7 years. Some substances (e.g. water) cycle much faster, obviously.

Which tells us that sentient consciousness and identity is mostly about the continuity of a signal across only some cells (nerves), and mostly rides on top of standing waves supported by those special cellular processes, at frequencies of oscillation faster than the underlying polarized/ionic chemical processes.

How do I know? I don't know what happened while on was sleeping. I fell asleep, and perpetually a few minutes later woke up, but my clock told me it was 8 hours. What happened??

You know what happens when other people sleep. It's not an issue.

Here's a great old animation on this topic

I can think of an experience. The kind of teleportation in which you (or your copy) is teleported too close in time and space and the original is not destroyed.

Then your copy claiming your job, your house, your wife and your children. Just as you would do.

Also if the transport process takes 20 lightyears, when do you send the ACQ? Will your original walk around for 20 years and then have an automated kill switch?

>Then your copy claiming your job, your house, your wife and your children. Just as you would do.

This sounds like a great scenario to me. I'm sure I would get along just fine with a duplicate of myself, and we could live together and get a lot more done. It sure would help a lot with avoiding burnout at work: we could take turns going to work, me one month and him the next month for instance. But two of us sharing one wife might be a bit much for her, so it'd be a lot better if we brought a second woman into the mix and lived as a polyamorous foursome (though this might be easier if we could create a teleportation clone of the wife too). It'd also be great having a double to help me on house projects, hobby projects, working on a side business, etc. And you mentioned kids: having an extra adult around the house to deal with them can only be a help, and since it's actually another me and not some other person, we're guaranteed to get along, have the same views on parenting, etc.

Honestly, I don't see any downside to this situation at all.

I would get a lot less [productive work] done if I had an exact duplicate of myself. My spouse would be jealous and disgusted at the same time.

But I am 90% certain that if my spouse had a duplicate, they would be yelling at each other all the time.

It would be interesting to correlate answers to the question "If you had an exact duplicate, with the same body as you, the same thoughts as you, and the same memories as you up until yesterday, how would you get along?" with various aspects of psychology.

The only problem I see here with your question is that no one really knows the answer, they can only speculate. I, for instance, think that I'd get along just great with my duplicate, and that we'd work together on getting more stuff done and enjoying more free time as a result. But I don't really know that; it's not like I've tried it before.

Why would your spouse be jealous of your clone? She'd now have two of you, so she's more likely to get attention when she wants it.

Why is it better if the original is destroyed? That's the whole issue here, the process in your example, when working as intended, just kills a person and makes an identical copy.
