Better training on recognizing and handling unreliable airspeed events has been a focus the last couple years at my airline, it can be eye opening even when you know something is up.
I will reserve judgement on this accident because I don't know the intricacies of the AN-148 FBW logic when faced with differing airspeeds and alerts. I would hope that full control would be available at the stick?
This is something we will need to know and understand as the next generation of FBW airliners come on line.
