This will lead into an open ended discussion of what it means to be human.
If an engineered machine is ecactly like a human what does that mean? Love, hate, greed, the capacity to say no and flip th bird?
In assert no human engineered machine could ever be human.
It would seem then that zoos are immoral. Chimps. gorillas, cats. We can deduce indirectly they feel. Beat a dog long enough and it will cower when you raise your hand. I saw it in a dig that had been abused. If robots have rights then so do many natural critters.
Animal genocide as a crime against sentient beings.

Sentience is the capacity to feel, perceive or experience subjectively.[1] Eighteenth-century philosophers used the concept to distinguish the ability to think (reason) from the ability to feel (sentience). In modern Western philosophy, sentience is the ability to experience sensations (known in philosophy of mind as "qualia"). In Eastern philosophy, sentience is a metaphysical quality of all things that require respect and care. The concept is central to the philosophy of animal rights because sentience is necessary for the ability to suffer, and thus is held to confer certain rights.

The desires for food and water, shelter and companionship, freedom of movement and avoidance of pain.[4]
Animal-welfare advocates typically argue that any sentient being is entitled, at a minimum, to protection from unnecessary suffering, though animal-rights advocates may differ on what rights (e.g., the right to life) may be entailed by simple sentience. Sentiocentrism describes the theory that sentient individuals are the center of moral concern.
The 18th-century philosopher Jeremy Bentham compiled enlightenment beliefs in Introduction to the Principles of Morals and Legislation, and he included his own reasoning in a comparison between slavery and sadism toward animals:
