Time travel is possible. And our future looks bright.

What am I talking about?

Well, if you visit Korea this year, you'll get a glimpse of technologies you won't find in the U.S. yet. You see, in the late 1990s, the Korean government invested in a nationwide high-capacity broadband network. Ninety percent of Koreans pay less than $30 a month for incredibly quick Internet service for their PCs and cell phones. In comparison, only 75 percent of Americans have broadband access at home, and relatively few have such speedy Web service on their cell phones.

Given this universal, superfast Internet service, companies like Google can offer Koreans the richest possible Web services.

Take, for example, the Google homepage that greets Google users in Korea today. It's animated. When you move your cursor over the icons underneath the Google search box, you'll see them jump up and down, helping to explain their purpose. Google doesn't offer this animated page in the U.S. because it would the page would take too long to load for many users.

Eventually, in both Korea and the U.S., Google may offer moving animations for the advertisements that it posts next to its search results, reports the blog SearchEngineLand.

Have you ever traveled to another country and seen a far-sighted technology that you expect will be soon adopted by the U.S.? Share your story with us, by posting a comment. Thanks.
