Here are my thoughts:

The internet is the most important thing to happen to humanity since the printing press. We've yet to see just how completely the world will be changed by this amazing system of tubes. There are so many examples of the incremental changes though.

Personally, I think that the internet is the first step in creating a unified world currency. Once everyone is online, we'll start to realize what everything is really worth. Since everyone will be looking at the same prices and bidding in the same marketplace for goods and services, we'll start moving towards a unified world economy and a stable idea of the what people are really willing to pay. Some we know what things are worth, then individual currency becomes pointless and actually starts to be inefficient.

Off-shoring is going to become more prevelant (like thats a big shock) but I think that as the global standard of living starts to rise. Sending jobs overseas promotes internationalism. Especially when we are takling about knowledge based jobs instead of manufacturing. These jobs also promote knowledge transfer in a way that factory work does not. Once knowledge is transfered and smaller less developed countries start to compete on an international level, we will see increased standards of living (and incidentally, increased proliferation of the internet.)

I wonder too if the internet will start to break down language barriers. Once economic barriers start to lower and the world becomes closer, I think also that less used languages will become even less so. Imagine what a disadvantage it would be for someone to not speak the more prevelant languages.

There's so many changes that we are seeing now and so many to come.

The internet is the means for bringing the world together.
