There's another phase we forget about. If I could choose, I'd like to grow up in a giant forest arcology and go hang out with my friends like it's a giant vertical mall with lots of places to go get lost.

When I finally got access to grocery delivery to my door, I could see how it all will work. Carrying things for one person is fine. It's carrying groceries for a household for a week where things break down. Even putting all that on an elevator would be really unwieldy compared to unloading from the garage.

Self-driving and the evolution of early-life education will play a big role in simplifying life without the parents needing to ferry the kids around five days a week.
