I feel like this post might be talking about the arrogance/humility axis, which is important but orthogonal to both dumb/smart and lazy/gets-it-done (depending, I suppose, on how you define those things).

Humility is necessary to say "yes, I'm smart, but there are the limits of that intelligence." Any smart person can learn enough C++ to get things done if they know Java, but it takes humility to say "I will learn C++ idiomatically and approach it on its own terms, rather than coding up Java paradigms with C++ keywords and libraries".
