> But my main point is that it’s absurd to accuse Airbus of overlooking an obvious improvement without even a cursory understanding of the matter.

Who made such an accusation? The only way you can assume that's my assertion is if you think the UI of an airplane is literally perfect already. If there is room for improvement, which obviously there is, it's not necessarily because anyone was negligent, it's because we're constantly learning and improving.

I find all of your arguments unconvincing and tied to the status quo rather than acknowledging that improvement is possible sometimes even in obvious ways given new information.

Just because there is the potential for poorly thought out improvements, does not mean that every suggested improvement adds a prohibitive level of complexity. You've failed to demonstrate that such a prohibitive level of complexity would be added with my suggested improvement... you've simply asserted it.

On top of everything, you've not provided any credentials showing you know any more about the situation than I do, yet you seem every bit as confident.
