Things like this always leave me feeling stupid.  How is one supposed to wrap their mind around the idea of space emerging from an underlying &quot;network&quot;?<p>What exactly is being networked; what is the &quot;stuff&quot; of the network?  He describes the network in terms of connections, which in my mind requires a topology, or space within which to exist; yet space does not apparently exist at this level.  If there is no space, then what separates the nodes in the network?  If no space separates the nodes, what defines the distinct connections between them?<p>Yes, i&#x27;m completely lost.
