IMHO you have raised a couple of very important points in your post. What's the point in flying an aircraft, of any size or configuration, maybe fitted with all the latest 'gadgets', if you don't understand them...or how to make them work for you?
I'm just a pedantic old fart who has been flying all sorts of flying machines since I was about 18yo...I'm 68 and a bit now., but one of my rules has always been...I don't fly anything that has anything U/S and I won't undertake a flight if the aircraft is fitted with anything I don't understand or can't operate to it's full capacity.
My log books show around 8500 hrs and I'm still around to bore the socks off you all, so I guess my system works to some degree.
The comment regarding instructors not knowing how things work is something I have come across in the past....sad, but true!
