Unfortunately what you are saying about their knowledge dying is true. Carbs will be around for years. But as EFI systems approach, and become cheaper then carbs, more folks will turn to the EFI systems. Younger folks seem less mechanically inclined and more computer knowledgeable. That will help drive the downfall of carbs. Now with the self learning EFI systems getting cheaper, I think you'll see more carbs going away.
Most, not all, of the fuel tuning you did with your engine being dyno'd, can now be done with the handheld from the EFI system.
I'm one of those that has moved away from carbs. Both my 67 Cutlass and my 70 GMC are running FiTech systems and I can honestly say I'm glad the carbs are gone. Driveability and performance has greatly improved with EFI.
