Lack of piloting skills is a definite problem these days. Whether that came about as deskilling (i.e. skills were there once) or whether the skills never were there in the first place doesn't really matter. The question is how can it be fixed?
Are we going to see much more simulator time, with crews hand flying several hours every month in less predictable scenarios? Didn't airbus suggest changes to sim runs to that effect?
Then ultimately we'd want more hand flying in real life as well, although statistics seem to suggest that may not be a terribly good idea.
It would be good if a more scientific approach was taken to deciding actions and lessons learnt from the spate of recent incidents. As blasphemous as that sounds, serious discussion is required about removing pilots from handling roles. There's no technical reason why airplanes can't fly gate to gate on autopilot, Airbus demonstrated that 20 years ago. The technology has been there for a long time. But that of course is an extremely contentious subject. Nobody wants to see the "avengers" retired... but that may just be the only way forward past the accident free 10m passenger kilometer mark.
