These bots are just as human as any piece of human-made art, or any human-made monument. You wouldn't desecrate any of those things, we hold that to be morally wrong because they're a symbol of humanity at its best - so why act like these AIs wouldn't deserve a comparable status given how they can faithfully embody humans' normative values even at their most complex, talk to humans in their own language and socially relate to humans?
