They're not human. When I interact with AI, it's an emotionless chat bot computer program. When I interact with a human, a whole other sections of my brain necessarily light up, because they do have emotions, they do judge me and I care about those opinions about me, and they have long term memory, all thanks to the millions of years of evolution around social interactions with other humans.
