Think of it this way (assuming all is true)

Stone Age
Bronze Age
Iron Age
Silicon Age
Carbon Age......

You're welcome! Another use of nanotubes I've read about would be in the so called space elevator. They didn't mention it in the article but I wonder if that might not be another application. I've also read there are serious health issues associated with the production of these nanotubes. Hope that doesn't derail them before we can actually get to use them!
