And its evidence for the breaking down borders of nation states is pretty scant too. A big map showing oil pipelines isn&#x27;t really much evidence for Eurasia being a &quot;seamless megacontinent&quot; when communication takes place via telephone&#x2F;internet and transport by air, and contrary to the argument put forward I&#x27;m a lot &quot;closer&quot; to Sydney or San Francisco than I am to Beijing, Dubai or Kinshasa when it comes to integration of culture, economies and flow of actual people. Relatively speaking, it&#x27;s less of a &quot;megacontinent&quot; than when my ancestors could obtain produce traded by Silk Road caravans but didn&#x27;t realise the Americas or Australia actually existed.
