Status Updates From Do Androids Dream Of Electr...

Just completed Chapter 1 and it’s interesting so far. I admire pre-80s/90s authors who are able to visualise a technologically advanced setting because it must be so alien. How do you describe a technology/item that has yet to exist for people to understand? Some of the terms used are also new to me and I can’t quite tell what it’s supposed to be but I roughly get the context of its use.
