Malabo & Crab,
When you apply Threat & Error management, I completely agree that training, experience and intelligence should enable a capable pilot to mitigate the many and varied threats in this environment, and not get into trouble in the first place.
However, technology has its place in helping you deal with the errors if you screwed up the threat management part. Its not a panacea, but its better to have than not to have (if you are properly trained to use it in appropriate circumstances).
