Drone delivery never going to happen; as I mentioned earlier laws and regulations will never permit anything like this to work effectively. We're asking the same questions from 10 years ago and still, no answers. There's a good case to be made for personal delivery services but there's no viable path to success. Seems like in the 2020s, all anyone wants to excel at is drone light shows and concept flying passenger drones and imaginary tech that nobody wants. I guess it's good to put on demos and show off vaporware but never have any intentions of building and deploying anything real in the near future. The smart people of today are more than happy to show off what can be done in a closed environment in the next 50 years but have no idea how to turn it into a business that works next year given the obstacles and the unknowns.
Same thing is happening with driverless cars and other tech like VR that we keeps talking about but nobody uses. The coolest drones in CES 2024 are the one outdoors doing the same tired drone light shows. Otherwise, the tech future is water generators, electric bikes, and little "robotic" gimmicky expensive stuff. I wonder how long we'll talk about AI before it actually does something productive that everyone can use.
