Very good point, Bloggs. And good to see A Van here.
No way can you compare the terrain warning of the commercial jets with those we had/have in the military implementations. We looked way ahead and even had a display that showed selected terrain clearance versus the terrain ahead - a side look "slice", if you will. We also had the "soft ride" and "hard ride", which determined how far out you had to pull up.
By the time you get the warnings in a commercial jet you better have the energy and quick reactions to do something instantly.
The CVR shall tell the tale,
