People-years is a measure I think we should use more. The International Space Station took the equivalent of 3 million people-years to build, or 26 billion work hours. Technologies don't just hold our morals, they're also the actual glue that holds societies together. To build something you need to co-operate. To maintain it you need to maintain that co-operation into the future, across multiple generations. Humans never agree, unless they build. Technology is democracy. Struggling democracies are societies that don't build things.
