Yes, again, follow the money. The push to have AI recognised as a legal person is to absolve the manufacturers or the owners of the AI in the case of accidents, injury, death or destruction of property.
Think about the idiocy of this. If you unintentionally damaged or even destroyed the AI, then you would facing charges of manslaughter or murder, instead of destruction of property.
AI is a construct, not a living entity.
That maybe true, at least when we are not able to give AI some kind of awareness. But what if at some point in time, AI is acting so much like a human, humans do not see the difference, humans get attached to AI like they can attach to humans, maybe even marry AI? At this point in time I simply cannot make firm statement, since we simply don't know what AI will be capable of in the future. I do understand the viewpoint towards AI you have; A viewpoint shared with many other humans on earth. Maybe we figure out at some point in time human awareness and consciousness does not exists as well. Although I primarily believe in big bang or big bang-like theories and evolution / evolution-like theories, I also find theories like Holographic Universe very interesting and maybe to a lesser extend the more popular theories around we living in a computer (although this theory is for me not plausible due to shift of the question who our creators is to another dimension).
