Yep! Completely agree with you, though at first gaze, drones seem to be a futuristic technology, in some countries, they are widely used not only for making professional aerial footage. Very soon, drones will change our world. Right now, they are wisely used by armies, firefighters, rescue crews, etc. As for the delivering of packages by drones, I heard that very soon, the drone delivery will be real in Dubai. I read this information in this article https://www.aeromotus.com/news/drone-delivery-in-dubai-myth-or-reality/ I think it will really be great, when you order anything online, you will have a chane to get your package almost immediately. Hope to see this technology in my country soon!
