Not the original poster, but the more frightening part of the sentence, is the "not understanding how something works part" over the "becoming my father"

Getting to a point where realistically you're not able to know something deeply but then still use it is pretty frightening.

When I say deeply I don't necessarily mean that for every device you need to know about all of its atoms, but to have a pretty good framework for how the thing works deterministically, and how it can fail.
