"The hardest part of being a machine is pretending to be human."
The way we perceive the world is heavily influenced by our past experiences and the narratives we tell ourselves.
The other thing about modern society and why it causes this anxiety, is that we have nothing at its center that is non-human. We are the first society to be living in a world where we don't worship anything other than ourselves. We think very highly of ourselves, and so we should; we've put people on the Moon, done all sorts of extraordinary things. And so we tend to worship ourselves.
