> digging a hole in the ground and then filling it up is horribly, soul crushingly demotivating. Europe can start reconstructing all the ruins of castles, monasteries and cathedrals; for example Napoleon destroyed quite a lot of them and most didn't recover. Or just tear down all the ugly buildings built between 50s-70s when architects were out of whack like some German cities are doing right now (Frankfurt) and replace them with some 3D printed aesthetically pleasing ones. Should be a plenty of work and those jobs could be opposite of soul crushing.
