> Bits cannot suffer, they simply simulate suffering.
Individual neurons do not suffer either. Yet, if you get about 100 billion of them networked in a certain configuration you give rise to a being that can suffer. If consciousness exists, it is most likely an emergent phenomenon that cannot be understood by reductionism. Your tamagotchi analogy is not accurate in this sense, it's like asking could a person who had a brain the size of a blueberry suffer?
> It takes biological matter to suffer.
I'd argue it takes a consciousness to suffer. It need not be the same as my own.
> Many animals experience suffering in a way much closer to humans and we by and large don't even concern ourselves with their suffering. Concerning ourselves with the suffering of AI seems so much less important to me.
Many people do concern themselves with their suffering as a moral imperative. Concerning ourselves should be as, if not more important IMO. The AI hypothetically can do something animals cannot do, it can tell us that it is suffering through language
