You know how people say that the more things change, the more they stay the same? Well, they're wrong. Things do change and then they change again. And if you're not changing -- you might as well hop into a time capsule! 

By mid-century, the percentage of non-Hispanic whites will decrease from 67% of the population to 47% and the percentage of Hispanics will increase from 14% to 29%. Des colores! 20% of the population will have been born out of the United States. The concept of national is merging into global.

Our perception of time and space has altered radically with the Internet and mobile phones.  The UN reported this year that 25% of the world population (6.7B) uses the Internet and more than half use mobile phones!
