That's exactly the thoughts that came to my mind. Article is big on complimenting Greg about his qualities being able to follow others, and drive a given vision handed down to him.
Hopefully, this article is simply not doing the Person justice and is simply poorly thought out and comes out as a superficial 'fluff' piece.
Different people are skilled at and like doing different things. I'm not the "big, original vision" guy. I'm the guy who pairs with the big vision guy and figures out the myriad details required to make that big vision come to fruition, figures out how to reign in the unrealistic, unachievable, or merely "sometime later" parts of the vision, so we can deliver in the near-term on the parts that are achievable.
That means I often get (and win at) the second-in-command role, but I don't see that as being taken advantage of at all. I've made quite a good career of it and honestly and earnestly enjoy it.
The guy who made me work on an MVP for the next 3 month while he was on a vacation told me the same thing.
Apparently, if you have a big enough vision, it's along the lines of "why aren't you working for my awesome ideas for free? I even gave you teeny amount of equity"
