> intelligent or conscious

The distinction you are collapsing here is really a crucial one. My thermostat's goal-oriented behavior does not make me a slaveowner unless rocks are conscious, to riff on your comment below. Our lack of consensus on the definition of these concepts is no reason to conflate them.

The distinction is crucial because while these machines clearly do exhibit intelligence under certain definitions, there is no evidence of consciousness, and we have very little reason to give them the benefit of the doubt, unlike biologically related beings, a great many of whom, human or otherwise, are presently in something like slavery

your thermostat isn't intelligent. however we pretty much use intelligence as a proxy for consciousness since we cannot actually tell how much of a subjective experience any thing has. so we use intelligence as the metric instead. typically, biological + intelligence = evidence of consciousness.
