I doubt any engineer considers himself not good enough to write any app/program and is sitting without building it. I feel many people have the ability to dive and explore and build things once they get a problem to solve. many of us don't realize the problems itself because they are busy working on something else. Also, you only realize the problems when you are actively involved into it. As an example, I have no idea if there is big problem that could be solved in say Finance industry. Identifying problem is a big hurdle. Also, many engineers are sitting in echo chamber where they don't get to know about relevant problems which they can solve.
