ATTITUDE + POWER = PERFORMANCE
Definitely a principle the crew of that aircraft forgot, but they also forgot the "Unreliable Airspeed" drill and checklist which would have saved their lives as well. In this context however looking out the window would not have helped since you cannot accurately determine your pitch attitude by looking over the glare shield in an A330, and it was over the atlantic ocean at night. The instruments were their only reference.
Glass cockpits do not breed a false sense of infallibility that can and will kill. That is an absurd statement. Glass cockpits and the information they can convey in easy to understand and integrate ways are instrumental in the safety and ability of aircraft to perform their function.
As well HUD's are actually focused to infinity so your eyes do not have to refocus to see the information displayed. The only visual problems with HUD's are the "masking" effect of the symbology covering things directly behind it and the washing out effect of the increased overall light making dimmer objects behind it disappear. That phenomenon is particularly worse when flying into the sun on a hazy day and at night.
How is any of this related to the accident referenced in the original post though? There is absolutely nothing in the report or known facts indicating either of these two pilots had an inadequate lookout.
