That’s the question I asked earlier today at Twitter. You answered a combination of new tech, like broadband and the internet; high-speed rail; and greater concentration, density, and walkability. Here with a sampling of responses from the twitterverse. I’ll add more as they come in:
carlos9900: the equivalent of the highways today are the broadband internet, public transportation, electric & energy system
jamesschwartz: We can learn a lot from China (I’m in China now). High speed electric trains and segregated cycle tracks
civicanalytics: Career pathway system with portable accounts for workers.
jamesschwartz: Bike infrastructure and electric trains!
JaceDeloney: Walkable Cities are the 21st Century Interstate Highway System. In a Post-Peak Oil world, urban concentration = innovation.
RobWebster: First reset – subways, second reset – highways, third reset – high speed rail.
BlandaNace: High Speed Wi-Fi and 4G cell networks.
