12.21.23 || Sometimes I look around at all the infrastructure that we've built: roads, bridges, buildings, ... A lot of this stuff has been built only within the last 150 years. That sounds like a long time, but at the same time, it sounds like no time at all. There's SO MANY roads, bridges, buildings, etc. that are built! It looks really difficult and time-consuming to build all of this stuff! And we built them all within only 150 years?! Society is amazing.
