I've used the phrase before, and I think it bears repeating, "Simulated Intelligence". It's probably a more accurate description, in the first place, to consider a lot of 'AI' examples as 'SI', in the first place and even while I'm not wishing to downgrade
true 'machine intelligences'[1] to merely electronic/whatever 'thinking machines', something that is recognisably merely doing 'Chinese Box' work is most definitely not worthy of rights[2].
Even under this restriction, there are still a
lot of possible different interpretations that individuals may care to (or purposefully invoke for mischief) to equate an SI with a sentient 'slave', of course. I would probably have a whole different viewpoint of an Intelligence that was a descendant of self-replicating Intelligences, even if I adjudged the original progenitor to be
our creation. Very Old Testament biblical, though[3].
I see far fewer problems in assuming (where prejudices are removed) that creatures (from other human races, in the 19thC example, through to dolphins and dogs and even plants) are as worthy of 'our' rights as we are, given that we have a common ancestor. Otherwise we come up against the paradox of assuming our 'humanity' (for the sakes of the rights we wish to convey) goes back as far as a given ancestor (or as far up as a given ancestor of the alternate line) but does not apply to their own parents (or offspring, on the way back up again). In a "how many grains of sand make a dune" kind of way, there's no real answer, once you start looking at the addition and removal of individual grains.
What might be
really tricky is dealing with known biological intelligences transplanted/copied into artificial housings[5], and in the recognition of intelligences that are life-forms using a totally different 'biological' construct and not from our own Tree Of Life (e.g. an actual silicon-based life, or a plasma-based one, where the corporeal presence and even the time-scales of interaction may be
so different). In one case we may have to recognise them as true individuals separate from the (pre-existing, and perhaps now non-existence) original to whom we had granted them rights, as opposed to a... I keep coming back to this word... 'toy'. In the latter, the difficulty is establishing that they are equivalent. And establishing
our equivalence to them[6]...
Oh yeah, and most recent poster reminds me, I've not voted yet, and probably will not for similar reasons as they've plumped for the "Undecided", only I remain even more aloof from giving an actual answer (even if it is
currently undecided, in all essence).
[1] And leaves the definition and the creation thereof as a still open question
[2] Protections from mis-use, yes, which are more the rights of the 'owners'.
[3]
...that leads into another philosophical parallel, as ArtificialAdam and ArtificialEve would be expected to do what we want and not stray, and be subject to Our rules but should we find them going counter to our intentions[4] and (instead of disassembling them) move them into a bigger 'sandbox' of the original work area, we might want to keep an eye on them as they diversify, and occasionally prod and probe them, even see what happens if we turn their world upside down or manipulate their environment to select for more compliant versions, while we had the will to do so. But we would probably still do this as Gods... And it is easy to visualise us bringing particularly suitably 'bred' SIs out into a more privileged 'sphere', when proven (either individually plucked up, or a large sample from the whole population when happy the sandbox has accomplished everything it can). And all this while they would be Our toys. And could not even begin to comprehend Our purposes.
And I really don't need to try any to push that analogy out
far further in that direction, but I'll stop now for the sake of not derailing us into an actual Religion argument... Just saying.
[4] Might not be their fault...
[5] Or even "Partials", from a series of books that I forget the name of/author, but are a "dedicated subset of id/ego/super-ego" that a person creates to perform various intellectual chores.
[6] Is it a Brian Aldiss short story where humans, (space-)shipwrecked on a generally benign alien world without all the accoutrements of civilisation, happen to be picked up by another alien race who assume they are native creatures of no extraordinary intelligence and caged in a zoo. Until they exhibit a certain trait (which I won't spoil) that makes their keepers realise that they're actually equals? And
how long was that question?
