Actually, there are only finite ways to fail. It just happens to be a large number. Thinking of interactions of the world as propagations of signals and considering Kolmogorov-style descriptions of entropy would lead one to this conclusion of finiteness. See: "Kolmogorov complexity"

Further, there are a finite number of patterns of failure, which is of course less than the number of absolute ways things could fail.

The biggest detriment is not that things can fail, but that people get overwhelmed by believing that such things are infinite in scale.
