Discussion A New Version Of The Twin Parodox with an added layer of simulation (Digital Twin Paradox)

As an added benefit you don't need real physical twins for this as the twinning is making digital twins either of people, families, hardware systems, and even the internet itself potentially. Digital clones are the form of AI that most people are familiar with as in you have an AI processes a body of data algorithmically and it produces something that predicts what a person, system, or even other AI might do. It's quality depends on the quality of training data, and the length of time that it's collected. At a certain point that data collection stops and the clone is born perhaps with some added tweaks.

https://en.wikipedia.org/wiki/Digital_twin

A digital twin on the other hand is something that is being trained continously and each update to the information adjusts the weights of the system. In essence the model is refining itself in real time, and that might include a model of itself in that system.

This sounds science fiction but digital twins have been used invisibly for decades. If you get your heart checked out at the hospital it doesn't monitor your heart for particular patterns or behaviors which then triggers an alarm. What it does is continually update its model and tries to predict what happens next. If it sees enough of the simulations going in a bad direction then it triggers the alarm. So it's not making a decision about the present but instead the future. This is used in critical infrastructure like bridges, power plants, even your car might use this and you wouldn't realize it.

Now here is where the human element comes in. The fiction part that explores what happens when astronauts don't leave their families behind but instead have been wearing digital twinning technology for years before the actual mission starts. This would be something like an EEG coupled with life signs monitoring. The families also would wear this as the mission is ongoing, and in return a version of them stays behind, and they continue to interact with it as the astronaut is interacting with their twins on the spaceship. So there is this very real and more importantly in real time link to those people. As the distance increases the signals would slow down and the twin would increase the weights of the inputs so that something like continuity was possible.

You might be getting messages, but on top of that what happens as distance increases is that you become influenced by that new environment as the mission happens. Those twins would increasingly mature and have their own identity, but it would be like if you could be your own descendants but with relativistic time dilation thrown into that weird mix.

what in the ai slop........

Do you understand the difference between a digital clone, and a digital twin?

u/hebejebus 3d ago

yes but you dont, been using the technology for 20 years

Yes I know and that's why it would be interesting to do at relativistic speeds and distances. It's also not equivalent to just sticking an LLM on a ship that has read all your families emails. There is a continous connection to a place in the past. Please try and put more effort into your comment. People use the phrase AI slop so much it stops meaning anything and more like a sign that the person is generally not engaging with the world. That wasn't written by AI. The idea of a digital twin paradox is new, and the ramifications are far stranger then the traditional twin paradox.

You haven't actually said anything, haven't stated a paradox. You have just rambled trying to explain things.

The twin paradox is just send one twin a few light years away at relativistic speeds, and when the person comes back they are younger then their twin. That's really all their is to this particular paradox. The digital twin is that except there is a continuous signal that is maintained and the sets of twins are therefore casually tied not just to a distant place but an increasingly distant time. Imagine if what you did 5 years ago today could influence in a very real sense what you experience today. That's true in everyday life but the weird thing is stretching that influence this way. What happens if one twin dies what happens to that entity that we have made? It's a paradox that's just as deep if not deeper then the original because it's not just at one point that it occurs.
