Those jobs require competence from most contributors. Mastery from a few. And you can teach mastery to non-incompetent people, most of the time. Also, most jobs that Ada would be used for aren't time critical (in the sense of "Oh god oh god oh god we've got to ship yesterday!", unless it's F-35, which fortunately didn't use Ada because that would've saved them a lot of heartache). They program in 2-5 years for the project so 1 month to competency and then additional OJT from more experienced (with Ada and the system) over the rest of the time will produce mastery.

True. I take back what I wrote for being too reductive. Well said.

I would doubt there are enough masters of C++ to fill an airplane.
