Some worldviews are becoming vapid in this global economy; industrialized versus developing countries is one of them, as it is increasingly apparent that innovation is flourishing everywhere. (Watch Hans Rosling's insights on poverty: http://www.ted.com/talks/hans_rosling_reveals_new_insights_on_pover...
The NIC also tells us that one big change of 2020 will be a shift in our understanding of the world. We won't see it as "West versus East." If Rosling's presentation of the data can help evoke that change quicker, all for the better.
The border instead will become: countries that are integrating into a global community versus those acting protectionist.
For that to happen, each citizen will have to respect cultural diversity and human rights. One cannot cancel the other out. For instance, women can have the right to wear veils and full-body burqas if that is their fashion choice. But if the act is a result of a society where love is stoning your daughter for getting raped, then it is no longer a cultural act you should respect but a human rights violation.
My hope is that the global interaction being fostered by technology today will help us all in 2020 to see each other's humanity, and to be interested and respectful of the cultural acts that guide each one of us in our lives.
