Being an old dinosaur as far as technology is concerned, I view these modern electric jets as technology for its own sake. You've got to have a degree of manual backup or you're stuffed. I prefer something akin to the 1-11 or 737-200. A modern jet has built in obsolescence in that it can suffer the same problems as an old jet PLUS the added complications of too many computers etc which can also go wrong and have more to do with economy than safety. And of course, I do a manual loadsheet every flight no problem. I agree with improvements to things eg more power and less noise etc but quantum leaps in technology merely because we can, have to be thought about carefully.
