Will there be crashes as a result; you bet, but there will be a lot less than if you allowed these low hour pilots to hand fly jet aircraft around.
Nonsense. Nobody is suggesting that one hand-flies when the workload is high; that is what the automatics are for. But there are plenty of scenarios where hand-flying proficiency can be maintained in safe conditions.
The whole point is that we must have the skills to immediately jump on the controls and continue to fly (or be able to monitor the automatics properly) when something goes terribly wrong such as AF447. The Turkish 737 was another example of automation dependency. I'll bet every one of those guys could to do a lovely 25° turn up and down in the canned Sim exercise. But they still got killed because they either didn't notice or could not work out WTF was going on. That's because they weren't current or in the mindset of actually flying the aeroplane. Handflying skill
does improve your monitoring of the automatics
and allows you to jump in and save the aeroplane when the AP spits the dummy.
What's next; autopilot and ATS becoming No-Go items?
Let's get out of this mindset of "experience is going down, so let's mandate more use of the automatics". Let's
increase training and recurrent proficiency to achieve and maintain the skill that will ultimately save our and the pax's lives.
