Everyone raves about fiber optic cables and instant messaging solving all our logistics issues, but they completely ignore the physical bottleneck of moving tangible objects. I have been reading up on the old postal pneumatic tube networks they had running under New York and Paris back in the late nineteeth century. It makes you realize how much we lost when we abandoned physical routing. Sure, sending an email is fast, but you cannot shoot a physical canister containing medicine, original blueprints, or a hot sandwich across a city in three minutes using a fiber optic line. We got lazy with digital packets. People argue that maintenance costs killed these systems, but I would argue we just lacked the foresight to scale them up properly. If we had kept investing in high-velocity air pressure grids, we wouldn't have delivery drivers clogging up roads today. It is a hill I am willing to die on, even if it sounds ridiculous. The engineering behind those leather-bound carrier capsules was incredibly robust, and we traded that mechanical reliability for fragile server farms.
