Does including a three-letter acronym (TLA) make your answer look informed (ALI)?
Because it's an article about outdated systems. Radio-controlled systems built in the last ten years, and in the future, are all mandated to be encrypted.
Furthermore, very few passenger train systems are radio-controlled. Instead, just like cars and buses, control is decentralized to the individual vehicle, and automated based on feedback from the track. No feedback, and the train stops.
This ist a standard and ancient sender/receiver problem of communication. However, I'm glad you like big machines and seem interested enough to dive deeper into this topic.
The official acronym TCS is still no match to your creativeness, please take it easy, as if you plan to do some research on this you will encounter a lot of those.
On the contrary, as if you under any circumstances should lose your intelligence - I hope not - you would not be considerate a human being anymore. And if there's a market for such, the incentive to give you a - cartoon like - hammer on the head would be there, too.
I mean that's already true to a degree. Pulling the plug on someone in a coma is a fairly normal thing. Unlike what you imagine a coma isn't a binary thing, there's degrees. When does it become okay to pull the plug?
People in a coma are still considered real human beings. The reason why you'd pull the plug is because there is no prospect of survival, or that the resources necessary are too great. Which, as much as it sucks, is a normal thing that happens. People die.
Intentionally breeding people that have no intelligence is a very different thing and I don't even know why we're talking about it as if it's even remotely similar.
Of course they are very different things, I didn't mean to imply otherwise. I'm just drawing peoples attention to the parallels that do exist.
> The reason why you'd pull the plug is because there is no prospect of survival
Same goes for a body bred to have no brain, surely. Of course that moves the dilemma to "is it ethical to create humans with no possibility of survival", which is a different question equally worth debating.
