Computers: clivada com what... is (C1)
Every generation has described the computer in the vocabulary of its anxieties: first a brain, then a bureaucracy, now an oracle. The metaphors matter, because they determine which failures we notice. When the machine was understood as a calculator, its errors were arithmetic and therefore checkable. When it became a decision system, its errors migrated somewhere less visible, into the selection of training data, the framing of the objective and the weighting of outcomes that no user ever sees. ___ is not the speed of the machine but the opacity of its reasoning, and the two are related: a model performs well precisely because it exploits regularities too numerous for any person to audit. Demanding an explanation may therefore mean accepting a worse system, which regulators are reluctant to say aloud. The interesting question is not whether machines will think, but whether institutions will keep using tools whose judgements they can neither reproduce nor defend when challenged.
