Touchscreens have their place
You can't really blame a touchscreen for the issue. You have to blame the interface running on that touchscreen. Split throttles on 2 different screens? Why? Did the manual throttles have 2 levers in 2 different places on the bridge to do the same? No? So why do it when you change to a touchscreen?
Moving to a different piece of kit doesn't mean you have to fundamentally change how everything works. Want to put a touchscreen in to replace a big button? Go for it, just make the interface also be a big button. Not have some odd UI that you have to navigate to get to that button!
