Yeah, the problem with drone deliveries is that they do not solve the main problem: last mole delivery. Whether it is a drone or driver, someone has to be there to pick up / accept the parcel. Since you cannot operate large drones in densly built areas, the number of parcels a single drone can deliver is limited. Compare that to the number of parcels a delivery truck from UPS or DHL can carry. Plus, such a truck does not have to return to base just because one parcel couldn't be delivered. For remote areas, military resupply and such, sure, drone will works just fine. But that is hardly a trillion dollar market, regardless how hard all those pitch decks try to make it one.
