One of the things I find irksome about the business world (and this won't seem relevant to the OP till I explain it) is that, while it places a premium on "finishing" and "delivery" (by the way, if you use "deliver" intransitively I will punch you in the face) it also makes it really rare that one can finish
anything. It claims to have a culture of "shipping" but employs these people called "executives" whose function is usually to get in the way of people trying to do so.
The disorganization of his "brilliant men" (which is a conflation of two types of people already-- the charismatic and the creative) seems to be something the corporate world (at least in 2014 technology) creates.
The "brilliant" just fall hardest, I'd argue, because highly creative people (one subtype he describes) tend to be most sensitive to context, and highly charismatic people (the other subtype) can usually assume the failure patterns of the highly creative.
The not-finishing culture, I think, is a product of the incoherency of the corporate world. It's not uncommon to see people pass years in Corporate America without achieving anything for reasons not their fault: shifting priorities, projects cancelled for stupid political reasons, "re-orgs", unclear direction.
At some point, people learn that Corporate Life is survived not by finishing (in fact, that can be harmful, because now you have support responsibilities) but being able to come up with a story when things outside your control stop you from finishing. The muddling effects of subordination compound this decline of executive function. It's rather sad, to tell the truth. I wish it weren't that way.
I don't think it's just "brilliant men" who fail, in this way, amid the jarring incoherency of most business. I think they just crash first and hardest. The rest tend to drift downward over time and underperform silently.
