Agree with the last few posts.
I personally think the Airbus FBW is a fantastic piece of design, and is well developed and thought out; credit to the design team. I find it a delight to fly and, coming from an old style basic jet, (the BAe 146), I found Airbus FBW easy and completely intuitive, (I do have an electronics background, and can appreciate why the system works the way it does - perhaps that helps).
I was type rated onto a B737-300/400 for a season two years ago and that was like something from the stone-age, by comparison. (Now happily back on A330 again, Covid 19 allowing).
As far as Dual Input goes and without contradicting myself, I would be curious to know the Airbus design team's reasoning on the cadet 'no flare' scenario and the other situation of not always being able to see the other side stick, particularly on a dark flight deck with the opposite tray table out.
