Ada also suffered from bad roots and bad timing. We're off a decade of simple dynamic languages. Ada seems like an old and immense ruin. Maybe there will be a julia/rust equivalent for Ada.
And it is very true -- Ada never truly gained any foothold in anything but situations where it truly delivered upon a requirement.
If anything, I can take solace in the fact that it is very much alive despite the exaggerated rumors of its death. I'd encourage everyone to try it out and steal all the ideas.
