I once went down the rabbit hole of thinking about how the targeting works on the TNG kind of transporter. Like they need to know to the molecule where your body ends and the rest of the universe begins. And you want it to identify clothing, because you don't want to end up nude on the other side. Plus it needs to identify what creepy crawlies are a part of you and which were just randomly wandering by. We don't want any of those pesky Fly problems now do we? This might sound easy, but is actually extremely hard. The human body is very complex and like a ship of Theseus what is part of the body is a bit nebulous and can change. All of the microbiome in our gut is essential for us to stay alive. And more importantly we don't want to leave behind a puddle of crap every time we transport. Plus what happens if we come out the other end, do our intestines just implode? Or does the transporter fill them with air, leaving you to fart uncontrollably until you die?
And how does it know what clothes are? If I'm wearing shoes, does it know where the shoes end and the floor starts? What if I'm wearing skies? What if I'm barefoot on a carpet? What if it's a leather carpet? What if I'm wearing shoes made by folding carpet around my feet?
The only thing that makes sense is a super powerful AI system that can real-time scan every molecule and figure out what's what. And it doesn't only need to be smart, it also needs a lot of real world knowledge. It needs to know what is "logical" to include in every situation. This means it has to be an AGI, has to be superintelligent (at a minimum speed wise) and would most likely be sentient. Them being used for this one and only purpose is really cruel.
This leads me to the conclusion TNG style transporters are basically slavery and put a whole different spin on the morality of the people in that universe. Thank you for coming to my TED talk.
Normally you need to put a coin in shopping trollies around here to take them out. When you properly return them you get the coin back. It's not a lot of money, usually 50 cents. And if you don't happen to have a coin on hand most shops will give you a key chain with a properly sized round bit of metal. It being so common, most people have one of those key chains anyways. I'd always thought it was a fine system, but people were pretty decent anyways.
Then during corona because of hygiene reasons shops could only reopen if they cleaned the trollies after every use and that meant not using the coin system. Later the cleaning part was delegated to customers using facilities from the shop and then got rid of entirely. But the coin system wasn't put back due to hygiene.
To my surprise people would just dump the trollies everywhere. They would not care one bit where they put them. Some people put them away neatly, some just shove them sort of in the right place. Others would just leave them on the parking lot or shove them aside to end up in a ditch.
As soon as possible the coin system was put back into place. Later some shops got rid of it again, because it's easier for customers. But only in select places where people are decent I guess, or the shop puts in the effort to monitor and handle the carts. You would think it'd be the crowded inner city parts where the coin system was needed. But near me in a rich part of town they use the coin system because rich folk just leave the carts in the parking lot, feeling like putting it back is beneath them or something. In a more crowded normal part of town one shop I go to doesn't use the coin system and I'm surprised every time. The carts there are always perfectly placed. Although that shop has an issue with people using the disabled parking spaces if they need to run in and out quickly, which is a terrible thing to do.
This whole experience changed my view of humanity. I used to think almost all or at least most people were decent. Trying to do the right thing, with only a few assholes spoiling stuff for the rest of us. It showed me that a tiny little coin, not really worth anything is all that stands between a functioning neat system and total chaos. And it's not just a couple of people, it's more like half of them. A lot of people are lazy and inconsiderate, caring only about themselves. If it costs them money, no matter how little, they will do what's required (because money is everything in this fucked up capitalist world). But if it doesn't cost them money, they will just do whatever and not care.
This experience, along with many other during the past 10 years have spoiled my view on humanity. I tend to assume everyone is a total asshole in some way or another, which is honestly kind of a sad way to live. So I make an active effort to give people the benefit of the doubt, but it can be hard and a lot of people shortly prove they are indeed assholes.
