Nice info, but we are not so close to flying taxi. I didn't hear anywhere good solution how to regulate short air traffic. It would be a mess if everyone is allowed to fly with their drones regardless they are for passengers or just drones.
ps. i follow you in faith for more this kind of content
Same is with Uber driverless cars.
Everyone thinks it will come soon but I have driven for uber and they even can't fix their map. I would die in a week (or lost driver license) if I follow their suggestions.
