The video above is more than a good song. It says a lot about the times we live in.
First, it's a collaboration among musicians in Africa, Europe, America and Asia who did not meet to record. They are singing the song of a Jamaican.
Many of these people come from poor backgrounds, yet they are able to use the same basic technology to make their contributions. See the headphones? Tracks are layered on tracks. The music is built using the Internet, the files passed around, additions made much as you would build a software program.
Which is the point. This collaboration was possible because people were using compatible technologies, because they had free interconnection, and because they shared a universal vocabulary.
In this case music. Other universal languages include mathematics, where equations look the same to a Chinese scholar or a Russian, and Java, which (like any computer language) uses the same structure whether you're Indian or Peruvian.
