your comment reminds me of when i interned at a large cloud services provider

i was very much infatuated by the idea of total reliability on a global scale and couldn't wait to talk about the CAP theorem with anyone who would listen. Read much of the research. I still love to flip through Designing Data-Intensive Applications by Martin Kleppmann occasionally.

As I was learning about said company's server racks there was a component that I asked an engineer on my team about – "Isn't that a single point of failure?"

He looked at me, exhausted and stressed out, and just said "Take it far enough, the Earth is a single point of failure."

I got the point.
