This is the first time I read Peter Singer's comments on AI.
He is commenting that possibly sentient/conscious machines should be treated as good as humans and animals, which seems quite logical to his thinking. However, by this simple interview, it feels that he is not really familiar with the topics related to AGI, machine consciousness etc.
In addition, he wisely comments also:
"It is also going to change the social landscape regardless of these machines are conscious. It is certainly going to alter employment. We have to think about what we are going to do when we get replaced by AI. We have to think about how we are going to support that society. Are we going to have a universal basic income? These are very important questions that we will be grappling with over the next decades."
