I sometimes think about informational life before the invention of effectively instantaneous communication aka telegraph. Before then it didn’t matter how important a bit was, it traveled at the speed of transportation on average. Best case was line of sight optical semaphore.

Civilization was designed around fundamentally delayed information flows. Want to track a shipment? That information could not really travel faster than the shipment itself. Want to tell someone you’ll drop by for dinner? Drop by now to tell them (or send another human)

Lightspeed communications create a temporal duality in civilization. States that can be synchronized instantaneously vs those that cannot. Materiality is non-simultaneity. The fact that a thing has mass is less relevant than the fact that it cannot be somewhere else instantly.

It’s easier to understand this in futuristic terms. If you’re chatting with someone from Pluto, it’s a 5 hour delay. Optimal way to talk is via duplex 5 hour monologues. The optimal way to use letter writing when telegraph and telephone are NOT options for escalation is forgotten
