Unfortunately these young guns just don't get it at all.
A very senior Training Captain used to call them "sons and daughters of the magenta line", it was and is a very good description.
It's all fine and dandy to fly the aircraft around following the magenta line with A/P B engaged but quite another to have the experience to operate outside the realms of their training (QRH ) when bad situations present themselves. Lately most of the bad situations required a skill level from the crews outside the norm training to get the job done. ( QF and CX to name just 2 ) Skills not learned from Microsoft Flight Sim or indeed a close reading of FCOM 3.
More importantly because experienced crews have been doing it for quite a while they have a lot more EXCESS capacity in their Brain to analyse what is occurring and work through the problems in a logical manner.
Over the last 30 something years as a professional Aviator I've seen young Top Guns and Old hands and guess which one I'd trust my families lives with???
Yep it ain't the young Top Guns.
