Folks,
If you read the articles, and others in a similar vein, it is not the bare "gauges" are the problem, but the much greater level of data available, to distract a pilot from:
Aviate, Navigate, Communicate.
From the time we (in airlines) got the first "electric" aeroplanes (B767 and the like) 30+ years ago, it rapidly became apparent that "all the bells and whistles" were very seductive, and it was all too easy to be distracted from the efficient operation of the aeroplane.
The border between
"need to know" and
"nice (maybe) to know" became very blurred, and as many of us know, it was often quite difficult to keep the "keyboard jockeys", the "children of the magenta line" hands off the keyboards in critical phases of flight. Do you really need an "extended centre line" entered by the keyboard, to turn onto final on a visual approach??
Also the propensity to forget Rule(1) of the "Computer Age",----
bullsh1t in, bullsh1t out.
This all happened in the relatively disciplines training and checking environment of airlines, is the GA record so surprising? In my view, first expressed in writing in the mid-1990s, it was all predictable.
There is now quite a lot of study on this subject, information overload is real, the airborne solution can all be boiled down (and this is not an oversimplification) to
"Keep it simple, stupid".
Tootle pip!!
