Unrelated, but there are plenty of people having above average knowledge that's good for real world use. Say 80% (if you define mastery as above 95%) Aside from being a software engineer. I also have various hobbies that I cultivate with above average level, graduated from 3 degrees in unrelated field, and know three languages. And I know there are plenty of people who do more than me. It isn't a stretch by any means. I believe plenty of people are very capable than what they think they can do. Human capabilities are more able than you think. Little by little knowledge compounds. i.e. if you can play guitar well most likely you can pickup bass quickly.
