Centaurus,
I would like to say that what you wrote is one of the most important and well articulated pieces that I have seen on this site for a while. Thank you for illustrating and sharing your insight.
Largely due to financial pressures of the industry, finding the balance between training costs and associated risk of crew experience is important of course. In the case of these airlines that have lost aircraft, the cost and pain for all involved has not been measured well.
The over reliance on automation is fact and needs to be addressed in a cost effective approach.
I have done research on this area and at times I feel safer in raw data at the 'what the' moments.
The high stall recovery techniques at FL510 are interesting.
