'changed the world forever', Yes, I'd guess globalization, especially, and ease of international travel will be greatly restrained. Globalization was already being challenged, since it has been bad for so many in the USA middle class and working class. CV may well bring many of those lost jobs back to North America from Asia. I think the Florida parks are going to lose a lot of the international visitors, due to both travel restrictions & world economic issues, for a few years minimum.
