D - We're falling behind!

In my last two posts I forgot to express my concern about how the US is falling behind China in key areas. For example, as the photo below demonstrates, China is in the process of creating "advanced three-dimensional transportation networks"!!! In the US, we only have two-dimensional networks! You've heard of the missile gap from the Cold War, well now we have the dimensional transportation network gap...

Well I sure hope they make it 3-D because otherwise only people from Flatland could use it.
