My fascination with bulldozers and differs is akin to my fascination with gas meters, with the added wonder of “hands no bigger than mine built this THING, this huge powerful THING.” And yet, even the largest machine can be defeated by a small thing. We are so powerful, and so fragile at once. Which is a good thing. Without the fragility, power becomes corruption in a heartbeat.

Yes, I’m feeling philosophical this morning. How could you tell?
