But Ada had for a number of years a mandate to require its usage [0]. That should have been an extreme competitive advantage. And even then, C++ is still used these days for some US military projects, like F-35. Though I don't know whether the F-35 is successful or not, if it is not, that could be an argument against C++. Ada is almost non-existent outside its niche. The main companies arguing for Ada appear to be the ones selling Ada services, meaning they have a horse in the race. I barely have any experience at all with Ada. My main impression is that it, like C++, is very old.
