I guess I forget that a lot of people have experience with only DJI drones and their brilliant - yet notoriously unreliable - flight assistance features.
I would not be comfortable owning such a piece of technology not knowing what to do in such a common situation as losing GPS signal.
My point is when it comes to flying, that's not "expert manual input".
Maybe one thing if you're whizzing around obstacles, but to stay relatively in place going straight up and down... Every pilot needs to be able to do that, even in moderate wind.
