This is an old argument. In the engineering world, it's been long known as SPOF (single point of failure). SPOF exists in many forms. It can be a physical part but can be protocols or people's beliefs. Google is kind of a SPOF for many people as well as your ISP. A media is a SPOF in many political systems. Some countries have only one national assembly, which is a SPOF too. I would call Euro (currency) a kind of SPOF, but people might disagree, etc. etc. It's an engineer's job to reduce SPOFs when it comes to engineering, but people in other fields are doing it too. It's just not called SPOF but crafting those systems should be equally respected as engineering.
