"We add a $70 surcharge to each delivery for the ballistic parachute system that protects people on the sidewalk from fumbled delivery handovers. This surcharge is refunded when the intact and unused parachute system is returned via the drone from your next delivery."

How do you shoot that used delivery parachute back to the drone upon next delivery?

DJI has those smart docking stations.

Maybe eventually each apartment will have one or it'll be subsidized by delivery platforms.

Food slides? Smart waiters? Hook and cook? And a large orange drink?

Pneumatic tubes

I'm disappointed society hasn't revisited pneumatic tube networks since we got good at packet switching and RFIDs and computing in general.

They're still used pretty heavily in hospitals and they do take advantage of newer technology like RFID for routing.

Separately, there's a very cool startup called Pipedream that does autonomous underground delivery robots that are kind of the next iteration of the concept.

But only for burritos. Pizza's not quite as resilient.
