I swear McLuhan has a time machine because !! this is a genuine concern of the working class!! Automation
threatens the livelihood of America's working class because their labor can be easily and cheaply replaced by machines.
To answer this question, I direct you to Kai-Fu Lee's TedTalk
here.
Kai-Fu Lee is a Taiwanese-born American computer scientist, businessman, and writer. He brilliantly wrote the book "AI Superpowers" and basically
answers McLuhan's question. If the circuits, machines, or automation replace our jobs we can just create new caretaking jobs
and humans can use our innate ability to empathize and care -- abilities that machines do not have.
