Unfortunately the way I see it, VNAV is one of the key drivers in the reduction in basic 'hand flying' skills. It's too easy and comfortable and you don't need to use your brain.....much.
I think the point 777yank was making was that given the situation the PF found himself in on the day, regardless of the reasons why he ended up there, VNAV was available to him as an aid to resolving the situation without killing two people and injuring many others.
