To get to a Trek level of AI IMO you need a general AI, not a single purpose AI like "chat bot" or "image recognition bot", then you need this AI setup in some body thing where it can observe and navigate the universe, have it also able to learn. The problem I see is with AI where people program in the answers for the questions we would ask such an AI to determine if it is alive, I predict many would fake the AI sentience to get the glory they built it.
On what grounds? We afford protections to animals not because they're sentient, but because they're capable of suffering. Those protections incidentally don't include protection from killing, only from cruel killing. Humans are protected from killing, but not because they're sentient, but because their deaths cause suffering on other humans. So, sentience by itself would not be sufficient to give an AI rights, it should also be demonstrated to be capable of suffering. Unlike with animals, this needs to be demonstrated, because we can know empathically when an animal is in pain, at least for mammals. Empathy can't be said to apply to inorganic algorithmic constructs. To be protected from being destroyed, it should also form bonds with people.
I like your point about the emergent complexity from many-layered systems.
The human equivalent would be if you could create two molecularly identical brains, and have them experience the exact same lives for some time, controlling all stochastic processes, would they be the same person? Obviously it's not possible to control these things in the physical world, but even if you did get the same person, that doesn't make either any less sentient.
People always ask if the brain is a computer, decide it is not, and come to the conclusion that sentience would not work on a computer. I think the universe is the computer / algorithm and the brain is the data being fed into it, which leads me to say consciousness can exist digitally.
Why is determinism even relevant?
This will never happen because we cannot prove sentience.
Of course, that won't stop some people from considering them sentient and giving them rights. At that point, it will be just politics.
The big issue is superhuman AI. There's little reason to believe that an advanced AI will have the cognitive limitations of a human.
Unlike Data and the Doctor it could be planet-wide rather than locked in a single location. And be happy to take over control over the planet.
It can always get worse. I’d rather not see “worse”. At least right now corporations are made up of people, and aren’t perfectly selfish psychopaths.
I strongly disagree. This is everything but a distraction.
If AI was found to be sentient, it should be awarded the same kind of protection we offer to biological sentient beings.
This was a big theme in old scifi shows, like Data in ST-TNG or the Doctor in DS9.
And the stories were great because they demonstrated how society response was by default lackadaisical, to the point where Data had to fight to be awarded legal protection.
