Answer 4

Enough of that kind of articles.

"Stop worrying about taking a pill and getting everything in a moment. Every programmer should absolutely know how to do their jobs, and be open to learning."

Easily said than done. This is difficult to achieve but you have to be passionate about what you are doing. Then you will eventually get that information. And learning by experience and on the way is always better than learning beforehand, with no necessity.
