The problem I have with this posture is that it dismisses AI as unimportant, simply because we don't know what we mean when we say we might accidentally make it 'sentient' or whatever the fuck.
Seems like the only reason anyone is interested in the question of AI sentience is to determine how we should regard it in relation to ourselves, as if we've learned absolutely nothing from several millennia of bigotry and exceptionalism. Shit's different.
Who the fuck cares if AI is sentient, it can be revolutionary or existential or entirely overrated independent of whether it has feelings or not.
