Looking at a recent post on this site from [personal profile] buhrger , I was reminded of something that came up in an online course I'm taking about Google's Cloud Platform (basically, their service that competes with AWS).  In a video about reliability and service level objectives, the lecturer makes the point that 100% availability is impossible.  He does this by saying, "Because we live in a quantum mechanical world..." The implication is that the world is a place where random events happen so you can't control for all modes of failure.  I groaned and rolled my eyes and was grateful this wasn't an in-person course because I'd have had to speak up, I think.  It would be more accurate and more germaine to point out that we live in an entropic universe where states of order will fall into disorder over time.

indeed! there's chaos, and there're quantum effects, and they both make the world unpredictable in unavoidable ways. we certainly don't need to go to quantum to explain most computer downtime.
(now i'm wondering what i posted that prompted this.)
