I would never work on projects that ADA is used for.
1. Would never work on "missile tech" or other "kills people" tech.
2. Would never work for (civ) aircraft tech, as i would probably burn out for the stress of messing something up and having a airplane crash.
That said, im sure its also used for stuff that does not kill people, or does not have a high stress level.
It's actually really great for anything where you want to be more safe/correct, like banking... and the `TASK` construct makes it really nice for naturally multitasking situations. A couple of the people in the community are putting together gamedev tools/engine.
