Would it make a difference if the laws of physics prevent or allow a machine from operating in 'duplicate' mode?

If teleportation machines were mainstream, I don't think they'd be optional for participating in society.

It's no different than going to sleep at night and waking up in the morning.

Of course. Fastest travel = best travel.

And the whole "you might die" sounds like big oil propaganda to me. I bet car accident deaths are way more likely.

[–] Hadriscus@jlai.lu 3 points 2 days ago

hmmm, I have to disagree there. Some of my best memories ever were made on trains and boats.

[–] Jimmycrackcrack@lemmy.ml 2 points 2 days ago

But it's not really the same kind of calculation as the car accident though. It'd be impossible to know if anyone using it ever had died from doing so, so impossible to compare the statistics and the concern is about whether the act of being teleported constitutes dying so depending on the answer to that the odds are either 100% or 0 (unless they have some kind of safety issue with more traditional, visible death or injury that bumps that up to something above 0% but below 100).

Fuck it, lets teleport. Who cares if death is the means of transport if continuity is maintained

[–] sploosh@lemmy.world 1 points 1 day ago

How do you guarantee maintenance of continuity? It would be impossible to prove.

[–] PonyOfWar@pawb.social 32 points 4 days ago (3 children)

Depends on whether they would work by actually moving me through space (using a wormhole or something) or by disintegrating me at point A and creating a copy at point B. In the latter case, I probably wouldn't use them.

[–] Apeman42@lemmy.world 16 points 4 days ago (3 children)

Yeah, I'd risk it walking through a Stargate, but the Enterprise transporter can fuck all the way off.

[–] dessalines@lemmy.ml 8 points 4 days ago

Like a solid 4th of trek episodes involve some sort of transporter malfunction. I'm not getting in one either.

[–] illi@piefed.social 8 points 4 days ago (1 children)

Only Stargate canonically disintegrates and then reintehrates you.

[–] eldavi@lemmy.ml 1 points 3 days ago

trek did too and by the most strict canonical definitions there ever have been in star trek too.

There's no difference. The universe could be destroying you and recreating you every Planck second, and it's indistinguishable from continuous existence.

[–] ada@piefed.blahaj.zone 5 points 3 days ago (1 children)

The problem with that line of thought is that even if it is true, it doesn't apply here, because when you create a perfect copy of yourself, you don't magically get a shared continuity where you experience the continuity of both the original and the copy. There would now be two independent chains of experience, and even if every chain of experience is endless destruction with continuity just being a trick of memory, there would still be two divergent continuities now, and one of those would end.

[–] Lemming6969@lemmy.world 3 points 3 days ago (1 children)

True but that's already happening in theory. All copies would argue they are the original even if their futures diverge. None would think otherwise or have an experience any different than our moment to moment continuity as it stands now. That's only apparent to a 3rd party.

[–] ada@piefed.blahaj.zone 5 points 3 days ago (3 children)

From the perspective of a 3rd party, it's a technicality. From the perspective of the original continued consciousness, it's not.

I am thinking of a case where it is 'disintegration' and 're-integration', but making use of some physics that prevent making a copy. For example, let's say that the mechanism relies on a step for which the 'no-cloning theorem' applies. In this hypothetical scenario, a commonly held belief is that the inability to make a copy retains the person's identity. It is a similar logic to how a person remains who they are from childhood and through adulthood despite the atoms that compose them changing over time.

I would encourage everyone else to use it. So roads will be less crowded and I can enjoy nature in its true beauty. Assuming of course Big Corpos haven't completely ruined it.

[–] Lumidaub@feddit.org 10 points 4 days ago (16 children)

I would. Never understood why people are scared of having their consciousness cut and pasted. I have files from 25+ years ago that have been moved between numerous hdd's, that's still the same file. (Always assuming everything works as intended, of course)

[–] ada@piefed.blahaj.zone 7 points 4 days ago (15 children)

It's never been the same file. It's been a copy of it. Which is irrelevant in every scenario, and to everyone involved, except from the perspective of the original file, and even then, only if it were conscious.

If we give the original file consciousness for your hypothesis, that consciousness gets duplicated to the copied files, but consciousness doesn't get removed from the original. And there are now a bunch of distinct consciousness streams, all of which smoothly continue on from the original, but none of which are the original. And if you delete the original, you delete that stream of consciousness, which makes no difference to anyone, except the original consciousness, for which, it's a cessation of existence.

From the outside, the copy is the same as the original. But from the originals perspective, not so much...

I mean at that point we probably have the tech to remotely pilot a James Cameron Avatar meat puppet, so I'd rather just do that.

And probably stay in the puppet all the time tbh because I would like to be tall and athletic. Hold the blue and alien parts tho pls.

I used to work with radiation and oh my GOD would having a disposable remote brain-controlled body be a fucking boon to that industry. Though probably at that point in tech history there will be very little if any need for human radioactive material handling

[–] CarlSagansMeatplanet@lemmy.world 10 points 4 days ago (1 children)

I imagine even if there is a strong philosophical argument that it’s a β€œyou die and it’s a copy/clone that comes out” in this scenario that people would still use it just from social and economic pressures. It would become normalized to work on the other side of the planet and just teleport there, your friends might be scattered across the globe, and not using the tech would put you at a massive disadvantage to everyone.

It’s a fun one to think about though - our consciousness is interrupted at different levels all the time (Sleep, injury, anesthesia etc), would a teeny tiny interruption from being rebuilt, make you any less you? Perhaps the scary thought is β€œyou” aren’t something continuous, and that teleporting (dying/being rebuilt) isn’t really that different than just normal living.

All that said - I’d probably grow up with the technology and use it while trying my best to never ever think about the details!

[–] SpicyAnt@mander.xyz 5 points 4 days ago

I think similarly...

Hypothetically: I spent my childhood and early teens using teleportation machines and I never had an issue. As a teenager, I learn about people who are strongly opposed to teleportation. People around me talk negatively about these people, and are perhaps annoyed at the laws that are made to accommodate those who choose not to teleport. They are seen as a nuisance because they complicate workplace dynamics because they don't want to do something simple and convenient that most in society do. The belief they hold makes most people uncomfortable because of the philosophical implication.

So, as a teenager, I realize that to become a 'non-teleporter' I need to accept that I have already chosen to destroy myself multiple times, and that my family and friends who leave are not the same that come back. It would be so difficult to make this philosophical mind-shift and stop teleporting so that copy #4,242 gets to live.

[–] Cethin@lemmy.zip 6 points 3 days ago (1 children)

For me, yes. I like the duplicator transporter thought problem, but I've always come to the conclusion that it doesn't matter. If what comes out doesn't know the difference, and the version left behind just stops existing, what's the difference? Maybe if the old version suffered from it I wouldn't, but if they just cease to exist then what's the functional difference between the two? If you believe there's a soul then maybe there's an issue, but I don't.

Is this before or after the great oil and transportation war has taken its casualties?

[–] SpicyAnt@mander.xyz 4 points 4 days ago

It is still possible to use regular transportation at a similar cost as today

[–] Bwaz@lemmy.world 3 points 4 days ago

Well, for a robust teleport function it should first make a duplicate of you at the target location. Check that it went well and if all good, then blast the original you into a cloud of red fog.
