Recognition isn’t the same as validation
Let’s start with pushing. Consider a tree of nodes. If we update one of the input nodes, our goal now is to find out which child (and output) nodes need to be updated. We’re not actually going to do the updating, we’re just going to find out which ones need updating.。safew对此有专业解读

Even Christopher Tolkien (so often the best and most reliable interpreter of his father’s work) shows a similar weakness in his treatment of the topic. In his explanatory notes, he takes pains to point out that the Daemon should not be understood as a Judeo-Christian demon, but rather as “an attendant or indwelling spirit” roughly equivalent to the Roman genius. By contrast, consistent indications in the tale show that demon is precisely the sense intended (guardian geniuses do not, as a rule, devise civilization-ending catastrophes, laugh at their victims’ misfortunes, or traffic with spirits in hell). The volume’s most glaring factual error is, curiously enough, likewise connected to just this question, and reflects the same general tendency of amelioration or softening. I confess that I find it difficult to account for all this. Perhaps the editors simply missed the point; perhaps they were indifferent to it. Perhaps, heeding Kilby’s warning that a frontal assault on Motores and the Machine would render Bovadium unappealing to mass audiences, they found it inconvenient. Whatever the reason, Tolkien’s most piercing notes are blunted.
