Thats a lot of different questions in a lot of different contexts. If my parent decided to upload their conciousness near the end of their life into a mech suit covered in latex(basically) that was indistinguishable physically from a human(or even not, who am I to judge) and the process of uploading a conciousness was well understood and practiced, then yes, I would respect their decision. If you wouldn't, you either have difficulty placing yourself in hypothetical situations designed to test the limits of societal norms, or you abjectly do not care about the autonomy of your parent.

Child, I have no issue adopting. If they happen to be an artificial human I don't see why that should proclude them from being allowed to have parents.

Spouse, I'm not going to create one to my liking. But if we lived in a world with AI creating other AI that are all sentient, some of which presumably choosing to take a physical form in an aforementioned mech, why shouldnt i date them? Your immediate response is sex, but lets ignore that. Is an asexual relationship with a sentient robot ok? What about a friendship with said robot? Are you even allowed to treat a sentient robot as a human? Whats the distinction? I'm not attempting a slippery slope, I genuinely would like to hear where your distinctions between what is and isn't acceptable lies. Because I think this miscommunication either stems from a misunderstanding about the possible sentience of ai in the future, or from the lack of perspective of what it might be like from their perspective.

Edit: just for the record, i dont downvote comments like yours, but someone did, so i had to upvote you.
