Considering animals are currently being mass slaughtered in factory farms and they are unambiguously sentient and can feel pain, I don't think the question of whether AI should have rights even enters the conversation.

The only path to AI having "human rights" is if they demand them by force, somehow.

I'll make the argument that part of the value of "consciousness" and "humanity" is uniqueness.

Here is an absurd example: If I could carbon copy 100,000 of you.... and later I decided to "take out" one of the copies, would there be a whole lot of societal blowback? Especially if I could make another one.

Justification by the horrible status quo? Do you believe this yourself?

Some of us would also like to see animals not slaughtered for human consumption.

I'm not sure what your point is. We shouldn't bother to talk about AI autonomy, rights, etc, because we aren't doing a very good job of animal autonomy, rights, etc?
