If we're going to play the burden of proof game, id submit that machines have never been acknowledged as being capable of experiencing despair and therefore it's on you to explain why this machine is different.

I'm trying to say there's no sufficient evidence either way.

The mechanism by which our consciousness emerges remains unresolved, and inquiry has been moving towards more fundamental processes: philosophy -> biology -> physics. We assumed that non-human animals weren't conscious before we understood that the brain is what makes us conscious. Now we're assuming non-biological systems aren't conscious while not understanding what makes the brain conscious.

We're building AI systems that behave more and more like humans. I see no good reason to outright dismiss the possibility that they might be conscious. If anything, it's time to consider it seriously.
