Eh? Not really a rebuttal, but more of a hopeless extension that

1. Smart and GTD is good enough hiring criteria

2. but for Unicorns™, you need to source and hire hyper-productive visionaries who nurture the right culture on top of having #1

Not very actionable, but hard to disagree that it seems to be a common denominator.
