Stuff like Ashby's ouvre is forgotten because it wasn't true. Ashby's Law of Requisite Variety? Not a law. Just a flowery proposition. The Good Regulator Theorem? Not a theorem, and not true. Just a Sokal-like appropriation of technical terms and mathematical argumentation style. I don't know where the presumable founding blog-post was, but there has been formed a subset of software engineers who, not being quite technical enough to see that this stuff is b.s., laud it as tragically overlooked. This comment is this phenomenon right on-the-nose
