It's my first time to have read about the drones to be used for delivery, https://thewiredshopper.com/drones-for-delivery/. I think this is a great idea, but at the same time, I can just imagine that a lot would lose their jobs. I mean, yes it so nice to have a quick delivery service, but I was thinking in the future, we might not have jobs anymore due to the continuous progress of technology. I mean it's not that I can do something about it, but I was just thinking about it. Any thoughts?
