Steam is good and glass is good, they are both telling you the same thing. even in the same format most of the time.
Not denying for a second that glass is good, nor would I ever deny that every single bit of information (if not a lot more) is displayed with glass. I'm not talking about the pros and cons of glass cockpits - they're fantastic.
My only problem is with using them for every bit of flight training from ab-initio onward. I can't imagine someone who's used nothing but the G1000 from their first flight onward would have their instrument scanning and general flight/IF techniques nice and sharp on a 1970's era twin with clunky old steam gauges from left to right if they'd barely (or never) flown them before.
I'm extremely happy that I did all my CPL/MECIR training on old stuff. Now - I'd be happy to take a glass cockpit any day of the week. Again, happy for people to disagree.
