I've said this before, and I'll say it again. One pilot ops buys you nothing. You need to demonstrate 0 pilot ops. You can only remove the pilot from the flight deck if you can prove that you can successfully (and more safely, and more economically) complete a flight with no pilots in the plane. Until you can do that, I think this is dead in the water.
Also, the Navigators & FEs going away is a poor argument from people who know nothing about the jobs they did. I've flown with honest-to-goodness human navigators, and I was an FE for years. Those two jobs are ripe to be taken over by a computer. The nav job was mostly math computations. Take a cell shot, do some math, plot your course. Do more math, tell the pilots to turn 2 degrees left. Repeat.
The FE job was even simpler. "When this light goes out, flip this switch." "If this light comes on, turn that knob."
Neither of those two job required much in the way of esoteric thought. All they were was data processors and, in the case of the FE, a human servo. Perfect jobs to be replaced by computers. Now the front two guys/gals... that's a different story.
