Major one missing: China built 5,000 miles of high speed rail in 6 years. In California, it's been 15 years and we have 0 miles complete. Also built numerous hospitals during pandemic in a couple weeks. Demolished and replaced a bridge in 43 hours: https://www.popularmechanics.com/technology/infrastructure/a.... General pattern of completing infrastructure projects at a blistering pace - and they work.Also landed a rover on Mars in 2021 https://en.wikipedia.org/wiki/Zhurong_(rover), but I"m not sure how it compares development speed to NASA. Designed for 90 days, lasted 4x that.As much as the US denigrates China for allegedly trampling on "freedoms," I bet our way of doing speedy big projects in the past has a lot in common with China's current progress. You just have to quash special interests sometime. Autocracy gets shit done.
