That is just how physical reality is. Everything breaks all the time and your process needs to be resilient to it. It is definitely the case that consumer 3D printers make that practically impossible though. (I tend to think home CNC is more interesting for this reason). For example, an industrial solution to some of the problems would be a checklist based inspection of the printer between every task, but this would be incredibly tedious. Software that has to directly interface with reality also has these problems.
