Immediately following the part you quote (my emphasis)<p><pre><code>  Well, as it turns out, thanks to the software-eating-
  the-world thing and the Internet of Things we happen to be

  demand for systems that are capable of storing and
  retrieving temporal data on an *ever increasing scale*
  necessitates systems that are specifically designed for
  this purpose.
