This may seem like a joke, but your answer will likely be in the vain of "conscious things are obviously conscious", which gets us nowhere.
I mean, self motivation and a desire to not be turned off can be programmed into even decades old AIs.
There is also apparently no real memory; if I tell it to stop doing something today, it’ll agree, then go back to doing it again tomorrow, with no memory of our conversation. This never changes, no matter how many times I ask.
Again we could debate consciousness forever, but in a simple sense, are there any other conscious beings without this sense of continuity? Not that I can think of. And so if everything we call “conscious” is different from an AI, then are we justified in extending it to AI?
[0] I lack a conscious experience and qualia
I’d be curious about how you’re showing they lack either of those
