Your comment is so profoundly wrong, and yet so confidently written. You're comparing Coke, a long-shelf-life mass market product, with (often) emergency/low-latency delivery of products which would be impractical to stockpile in every remote village, even if they could affort it (e.g. certain types of medicine and consumable medical products, blood, etc.)

Coke doesn't need low-latency delivery - they can use high-bandwidth + warehousing. This isn't possible/practical for some types of products.

Unless it is a AI powered blockchain drone, that would be unbeatable!

Drones are much faster than cars at getting to remote places. There are many, many villages throughout the African continent that can take several hours to get to due to lack of paved roads (you need a 4WD, and it'll be a bumpy, slow ride). Sometimes the territory is dangerous to drive though. Drones can also be used even in more developed areas when roads have been completely washed away by a flood/hurricane/landslide/etc. The industry certainly has been hyped, and it's still early days, but your claim that they're not useful is absurd.

Consider a rarely needed but life-saving antivenom that is expensive to produce, requires careful+chilled storage and is just not that abundant outright due to difficult production. A snake bite could happen anywhere, but its infeasible and potentially wasteful to have it stocked at every local facility. If a drone could be used to deploy it from a central facility to where its needed in a timely manner on-demand, that could save lives. In the developed world, roads make ground transportation a more suitable approach for this problem (in addition to everything else that makes the problem itself less frequent), but in many parts of the world the ground infrastructure is simply not there.
