There are still pretty serious technical and engineering hurdles to overcome to make this kind of idea feasible. It was always hype without substance. But even assuming these challenges were overcome, which is inevitable eventually even if it's a century from now, I get the feeling this would largely end up getting banned in many places. I think regular people hanging out in their backyards and going for walks in the neighborhood would feel a vague persistent menace if there were constantly drones zipping around overhead. Think about the fact that you can load up a delivery truck with hundreds of packages at a time. Drones don't have that kind of cargo capacity. The fleet would need to be massive to replace truck deliveries. The sky would be full of them.
