and even conscious animals are killed in factories by millions so why should anyone care about a llm?"
Well, I would care, if they soon would possess the capability to hack into the nuclear arsenal and kill humanity. Or make all autonomous cars crash. Or do any other thing, that involves technology and is hooked up to the net in one way or the other (I hope all the nukes are not).
But I also care about the animals, I am sure that they have feelings. But they cannot kill us. AI that might or might not have feelings potentially can. I just know it feels wrong, that computers can have feelings. But they surely are potentially dangerous.
