"When robot pilots become safer then humans, why would you insist on having a human?"
Because most people are not rational, particularly when it comes to flying and fear, or indeed relinquishing any kind of control to a robot! I would put money on it that even if a robot was doing the flying, the general public would insist on there being a trained pilot sitting in the cabin just to keep an eye on things!
It doesn't matter how statistically safe a robot piloted plane, train or car could be people are going to be a bit wary of it because if they cannot drive themselves, they would rather delegate the responsibility to another member of Homo sapiens rather than a collection of wires.
That's just one of the irrational animal based tribal responses which makes us human! Maybe it will not be always and until the end of the universe/human race - but it'll be a bloody long time till people get over it!
