We build a million things each year which are a lot more impressive than cathedrals. China built a entire high speed rail network that's about the size of all the other ones in the world, combined, and they did it in 20 years. China built a high speed Maglev train between Beijing and Shanghai, I think Japan is going to build one soon, too. The US has been building hyper tall pencil looking skyscrapers in Manhattan for about 20 years. There are tons of amazing tunnels being built around the world, as we speak. India, China, Indonesia, etc. are building amazing subway networks in tens of cities. The scale, complexity and sheer audacity of what we're building has never been seen in the history of the world.
