Interesting article.
I expect countries-- as geographical and economic constructs-- will gradually cease to exist and be replaced more by an assortment of global "tribes" based more on common interests, values and belief systems, but not on geography. Maybe they will be "techno tribes" or "guilds" that exist as conglomerations that beyond such things as nationalism... now whereas I think they will end up superceding "nations," I'm not sure whether they will be able to escape dominance by "corporations."
That's a really different way to look at things and I like it. It can definitely happen that way. Technology has rendered geographical locations obsolete anyway.
