GF,
Well clearly your intimate knowledge of Gulfstream engineering is spot on, nothing has changed since the Beatles were making records, but just like Paul McCartney keeps selling out stadiums, Gulfstream keeps selling airplanes, they both must be doing something right!
As for the former BD700 pilot who for some reason abhors the idea of having to occasionally make a decision for himself, and God forbid, having to lift a finger to do it, I doubt he won't be happy until he gets to fly an airplane that has just two switches, one labeled "On/Off" and the other "Take-off/Land".
In the meantime Gulfstream will continue to build airplanes that actually meet or exceed their design performance expectations.
