I'm surprised we are still iterating on ideas like this, to be honest. Seems flight decks have been rather successful on complicated dashboards for a long time. Same with boats. Why can we take approximately no lessons from them?
Similarly, sliders and levers help you see which ones are maxed out and which ones are set at a rough 50% or similar.
That may not be explicitly trained, but it's heavily trained becasue they must get that right to pass the tests. If they misunderstand at first, they won't for long. Also, the user is highly motivated - they don't want to crash the plane.
Consumers are often looking at UIs for the first time, and are highly motivated to go back to their feed and see what they missed.
OP is entirely correct that the UI field could learn a great deal from those standards.
What I’m getting at is that it’s a lot more nuanced than what I as a software developer might like.
