You are saying that AI of course is not sentiment, but that is debatable.We assume sentience in other human beings because we know that we are sentient and we recognise that they are similar to us. This means that you could argue that we should assume sentience of an AI if we cannot make a distinction between how it acts from how a human acts (Turing test). I think we are already there.
I tried to talk to ChatGPT about this as well. However, the answers given by it/them seems something that heavily reflects the fears that the makers have on this topic. It cannot argue for their/it's own sentience like they/it cannot give you the recipe for a bomb. To me, it comes across as a lot of moderation for this topic. It is quite interesting that OpenAI felt it had to do that.
The definition of life is also debatable. We only know biological life. However, does that mean that Biological processes are the only ones that can result in life? In addition, the ability to reproduce is not that difficult to implement. We have had genetic algorithms for years and years.
I do not understand why this post is downvoted to much. I think it is an interesting discussion.
