The last days worth of posts is very scary with type rated pilots arguing to this extent rather than discussing.
In the end it's the updates to the training that is important as warranted ,and not individuals yelling at each other over postings.
The investigation will sort out the parameters that occurred and the analysis will sort out the possible what-if effects on those parameters. If the aircraft was as some have stated unflyable after the pitch up (nothing could be done?) then all that's left are recommendations (either reminders or updates) for how not to get there in the first place. If the data supports the possibility of an escape maneuver than I would rather look to the Manufacturers (Boeing) to suggest the action than read the acrimony like just occurred today on PPrune.
