Except it doesn't scale. Amazon, Google and Netflix (the companies referenced before this quote) can't run their applications on a single machine. Distributed programming is unavoidable at scale.

Networking might introduce a longer delay than a CPU call, but if each one of those calls does significantly more work, the overall performance of the system can increase.
