One map shows the crazy supply chain journey of your gadgets

When Parag Khanna pictures a world map, it's probably not the one you or I might imagine.

That's because Khanna, author of "Connectography: Mapping the Future of Global Civilization," thinks it's far more useful to separate countries by their connectivity borders than by their geographical ones.

A recent map tweeted by Khanna makes his reasoning plain to see.

The map, which lays out the world's supply chain for products we use day to day, from Apple iPhones to Toyota cars, reveals a stunning crisscrossing between continents.

Each point on the map represents a location where the specific products travel before they reach consumers. Apple iPhones, for example, start out as loose parts in the company's factory in China. From there, the assembled phones travel to Japan, Europe, and North America, where they're distributed locally — those are the red arms reaching from the east.

Interestingly, only a handful of countries serve as these manufacturing hubs. As Khanna noted in his TED talk last month, the world's major economic powers are getting more and more clustered. It's only a matter of time, Khanna argues, before megacities (those with populations in excess of 10 million people) are the dominating force in shaping the world.

"Connectivity, not sovereignty," Khanna said in his talk, "has become the organizing principle of the human species."

That's as true for major political decisions as it is for hybrid cars and blue jeans.
