These are some very interesting ideas. I agree that many jobs will be replaced by machines and that our jobs will mostly be creative in nature. For instance, 3D printer technology would allow individuals to place an order for nearly any type of product, which could then be 3D printer to order and delivered by drones to a place of residence. Humans would no longer be required for manufacturing but rather for creating new ideas.
Personally, I am not sure about the idea of everyone working from home. Human beings are a social species and human connection is one of the most important aspects of our happiness. Humans may want to leave their homes and work directly with others simply to connect with others. There are of course many ways that humans can connect with each other but face to face contact seems like it would always remain valuable. However, in the world that you speak of, perhaps there would be more leisure time and individuals would actually have more time to connect with people that they are truly close with. How do you see human beings connecting with others in the future?
