I think you may have misinterpreted someones apprehension about "black-box" syndrome to mean they are anti-technology. There are a lot of great inventions out there and a lot of great technology, but when those systems don't work, you are left with a clock and a map. If you have the basics down, then you can do the J-O-B whether you have any of the new tools or not. Same goes for TCAS and some of the other technology out there.
However, it would be nice to stop piece meal upgrades of E-models and get something that makes all Herks the same. Unfortunately, politics and economics won't let that happen. I've been around for the C-130X and Y discussion, the J-model that should have been fielded faster and all the other shenanigans that have taken place in the Herk.
I can tell you that the use of the term 'legacy' really gets under some dudes skin. I'm not one of them, but I have several friends who really have a problem with the term. Anyway, that's another discussion.
