People who Get Things Done but are not Smart will do stupid things, seemingly without thinking about them, and somebody else will have to come clean up their mess later. This makes them net liabilities to the company because not only do they fail to contribute, but they soak up good people’s time. They are the kind of people who decide to refactor your core algorithms to use the Visitor Pattern, which they just read about the night before, and completely misunderstood, and instead of simple loops adding up items in an array you’ve got an AdderVistior class (yes, it’s spelled wrong) and a VisitationArrangingOfficer singleton and none of your code works any more.

The startup ecosystem is structured along the lines evolutionary biology: it fosters random mutations and rewards the winners with growth.
In an evolutionary system, Getting Things Done (creating mutations) isn’t a winning formula, it just table stakes. To win you need luck and / or smarts.
