They might, but they might not.

Trees have been given rights in some places. Some people believe dogs and cats have rights.

Humans have been not given rights in some places. Some people believe some humans don't have rights.

It's not about "sentience" or "consciousness" -- in reality, these concepts are religious ones, like the soul, and don't map to anything objectively meaningful.

A better way to think about rights, I think, is that they stem from the barrel of a gun. Can a thing reciprocate a social contract with me usefully? Can it help me if I'm nice to it? Can it hurt me if I'm mean to it? Alternatively, will entities that can help me do so if they see me help this thing or harm me if they see me harm this thing? That's all that matters; I'll be game-theoretically forced to grant it personhood. I'm programmed by my brain to show empathy to you, and, when that fails, you or others will harm me if I hurt you. Or, if I become a powerful dictator, I might execute you for being inconvenient to me. For all I know, you're a p-zombie that I could otherwise hurt with a clean conscience. None of that really matters; it's all about what I'm forced to do, from within or without.
