It's not quite the same thing, as the network is not any denser, it's more efficient. I can't quite find the right metaphor in computing as I imagine the human creators made things pretty efficient even with valves and transistors. Perhaps a good metaphor would be that of the flow of water in a branching braiding swamp near the coast and the flow of water in a mountain river.
