That being said, we should really take these anecdotes with the appropriate grain of salt. After all, we're here in a thread about countless companies being threatened by security flaws. A dev that "gets things done" (from a business point of view) might actually do that, but do they also think about all those other requirements that business themselves can neither validate nor appreciate if measured by short-term KPIs?
I'm not saying that's happening, but I've seen too many "Why are you spending weeks on this, I can do this in half a day!"-kind-of-devs, that then hack something together that technically works as the requirements demanded, but completely falls flat under any aspects of maintainability and extensibility, let alone security.
