The complaint isn't that logistics should follow Moore's Law or that we need same-day delivery for everything. It's that we're paying more for objectively worse service than we had a decade ago. Services aren't "adapting to consumer needs", its just objective decay being masked as optimization.
The Lettre Verte example actually reinforces the point: service got slower, then slower again, not because physics demanded it but because maintaining the previous standard became inconvenient. The dedicated sorting train wasn't decommissioned because trains stopped working; it was decommissioned because the institution decided the mail didn't matter enough to run it.
Nobody expects sea transport to break the sound barrier. But when 73% of consumers experience an outright delivery failure in a three-month period, that's not bumping against hard physical limits. That's drivers marking packages "delivered" that weren't, because lying clears the route faster. That's solvable. We're just in a system that doesn't incentive fixing it.
The asymptotic argument would land if we were approaching some theoretical maximum. We're not. We're sliding backward from where we were, while costs rise. I'm not asking for magic, I'm asking where went the reliability we already had, at the prices we're already paying.
