As a non-piliot I find it really strange that modern aircraft do not have any warning systems associated with the airspeed. Hundreds of aurals/alerts yet no warning about the airspeed. A simple warning horn can be a big help in certain situations me thinks.
Well, if the presence of auto thrust is having an effect on crews such that they are abandoning basic airmanship and failing to monitor airspeed for the length of time implied by the preliminary results of this accident, then sad to say I fear you may be right.
There are perfectly adequate visual alerts to warn the pilot of dangerously slowing airspeed but simply put from a professional pilot's perspective, if no one is monitoring airspeed then no one is really flying the aircraft at all.
