The training *makes* it instinctive - it's the whole point of training.
Rananim - I know how you feel about cockpit automation because we've butted heads over the subject before. I'm more than happy to agree that the AI FBW does have some drawbacks as well as numrous advantages, but a lot of the perceived disadvantages that you bring up are more to do with your distaste for what you see as marginalisation of the pilot than actual, known problems with the design.
Boeing didn't consider changing their flight control input method for financial, not technical reasons - they already had 5 or 6 jetliner types in the sky to maintain as much commonality between as possible, whereas Airbus, who had 2 (effectively one, A300/310) did not have the asme baggage. Of course, the press-induced backlash in the wake of Habsheim and Strasbourg as well as a distaste for FBW by some in the pilot community probably strengthened the case for them. But still, their latest offering is full digital FBW with a computerised backdriven force-feedback system - just as prone to problems as the A320 digital FBW setup.
