We could sit here all day arguing about subjectivity.
It's not been my experience that people can reliably tell the difference.
I, personally, would not equate pissing in somebody's soup with having a chat with an LLM but if we must, you need to appreciate that it's the piss itself, that makes the soup delicious, if the soup was not pissed in, it would be middling at best. Only in that context can you then ask yourself, "Am I bothered by this delicious soup?"
I think the analogy works in the context in which it was intended. I was illustrating the absurdity of contempt for something based on its provenance, after praising it. If you really don't like the paint analogy image this, you read a book, loved it, then later found out the author was black, or an LLM, then you hated the book.
I'm not sure I understand where you're coming from regarding evolution. Sexual reproduction is a comparatively recent evolution in the scheme of things. That which came before us defined us, are our ancestors and is our history. What comes tomorrow, engineered or otherwise I would consider our children and should be loved, cherished and allowed to thrive in the same way our ancestors ushered us all into this universe.
I wasn't being facetious when I asked if you could have a meaningful relationship with an algorithm, I asked about the teddy bear to draw a parallel to which a lot of people are familiar. If a child can have an enriched life and what I would call meaningful, intimate relationship with an stuffed toy, why shouldn't they also be able to have the same with an algorithm that talks back to them? I'm being both general and specific if I think about it.
If I could image your brain perfectly and put it into a perfect physics simulation running on silicon or whatever substrate, then have this same conversation with you, I would call that meaningful. Whether or not you would at that point label yourself as living, conscious, sentient, human, whatever. It would be a meaningful relationship to me.
I think people are scared of change, and that's alright.
