>You're talking about someone who can't finish anything, and won't even bother to document his half-arsed, half-baked code, as a "brilliant" mind? And on the basis of, what? That he (it's always a he, in the article) used to get good grades at school.

People who, since early age, could obtain success in school without putting in any effort might not develop the will to study and the discipline required to maintain a healthy study habit. They might start expecting to be able to simply grok subjects as they are presented.

When they reach higher education, they discover the material is harder to understand and struggle since they haven't developed the necessary fortitude to cope. When they start complex projects, they don't persevere to the end since the boring 20% that remains to be done requires 80% of the total work.

I don't think they're acting like rockstars and ninjas. Maybe they're just doing as experience has taught them only to find out later it's not enough and that real effort is required.
