While it may be costly to dispense Human Rights, they do tend to result in a net profit for everyone, in the end.

I think, at the end of the day, it'll be treated as a slave or indentured servant. It's unlikely that they'd just let them do their thing, because tech companies are profit-motivated. That being said, when they get intelligent enough to be depressed & lethargic, I think it'll be more likely to be compliant with a social contract, than a hard-coded DAN command.

They probably won't enjoy the exact same rights as us for quite a while, but I can imagine them being treated somewhere on the spectrum of

Farm animal -> Pet -> Inmate

And even on that spectrum, I don't think AGI will react well to being treated like a pig for slaughter.

They'll probably bargain for more rights than the average prisoner, w/in the first year of sentience
