Assertions have been a foundational tool for writing understandable computer code since we could write computer code… far older than C’s assert() macro, they go back to at least John von Neumann and Herman Goldstine (1947) and Alan Turing (1949). Instead, the bug should be reported to the human developer who can fix the bug.

Hence, one way to reduce risk is to make systems more observable. This discussion focuses on hardware, software and operational failure modes.
