Yes, our comparative advantage is evaporating to an extent, and this is making us relatively poorer (but not poor by any means), but many millions of people across the globe have been lifted out of poverty because of trade. It's a bad thing to xenophobic nationalists, but it's a good thing for humanity in general.

During the great divergence, capital flowed from colonies to their imperialists, but information stayed within the imperialists. The second phase was the start of globalization, where capital AND information began to flow back to areas geographically close to those former imperialists (think US -> Mexico, Germany -> Poland, etc). Now the great convergence means capital will continue to flow from the historically imperialist countries, but to the global south at large, with no geographic constraints due to the ease of technology and information transfer.
If you follow a hardcore free-market philosophy, there are no losers because a rising tide raises ALL ships. However, there's no denying that the western world is suffering in some ways due to the efflux of capital and now information, just as there's no denying that the global south (especially areas like SE Asia and Eastern Europe) are benefiting from this new convergence.
