Skrodes. “The skrodes (…) are devices which can be made everywhere in the Beyond (…) but their design is clearly High Beyond or Transcendent. (…). He had looked at the design diagrams – dissections really – of skrodes. On the outside, it was a mechanical device, with moving parts even. And the text claimed that it can be made with the simplest of factories (…). And yet the electronics was a seemingly random mass of components without any trace of hierarchical design or modularity. It worked, and far more efficiently than something designed by human equivalent minds, but repair and debugging of the cyber component – was out of question.”. Layer Review. .
