It's been treated as an irrefutable endpoint at best and as a spell at worst. I find it a convenient false authority for lazy thinking.
Consider a statement like: "an expressive programming language is necessary to manage a resource distribution system such as a food production, processing, and delivery system." One could quote Occam and say "nah let's hunt and gather," but how is that consistent with our values? Ergo, Occam's quote is a selectively applied false authority. We need to use our heads and put it to bed!
