AR/VR will enable more spatially interactive technologies as well. Pokemon Go was a fad but I think it heralds a yet-to-come wave.
The suburb hate bandwagon on here has gotten way out of hand. They are not inherently unsustainable and it is not a "waste" to spend a bit more resources to make a space that's nicer to live in. Not everybody wants to have to walk everywhere/take public transit and live like a sardine in a can getting accosted for spare change all day. And are you saying you'd really let a kid "explore" in a city? You're not even particularly safe in a "walkable city" as a lone adult if you go down the wrong street or you're not paying attention.

I noticed that the author mentions that a busier city street is safer from violent crime but doesn't acknowledge that very busy streets are also havens for pickpockets, whereas you generally get it both ways on mostly-vacant-except-cars streets in lower density areas with little to no violent crime.
And similarly the notion of "place" is melting in this era. No more music shop, useless, you can buy a Trillion things on whatever. Same for toys now. But I think humans have a thing for local space. Culture in a way. Every shop used to be customed in weird ways. Some people would waste their time there and find things randomly. They would discuss with owner tastes. Going to a toy store was a treat in itself, even when you couldn't get one.
Right now they're going away, but like vynil some will reopen when people miss them too much.
