When you actually make something rather than simply being an intermediary, your potential for growth is determined by the limits of what you can build. An intermediary like Google or Facebook or Groupon are eventually going to fade away, being replaced by the next shiny new thing.
Apple may also fade away as may Microsoft but their impact on the world will be much more far reaching.
