The breakthroughs made by a matter of some hundreds of men genetically-originating in Western and Central Europe over the past several centuries have affected every person in the whole world.

The exploitation may be so rapid that the name and even the existence of the genius has often been lost to history, or never known.
While it may take a one in ten thousand persons to make a breakthrough; the ability to recognize and use the breakthrough may be much commoner - one in a hundred, even one in ten...
Intelligent un-creatives are, I think, those relatively-few all-rounders among high IQ people: those high-IQ individuals with balanced abilities - including a pro-social (compliant, docile) personality .
Whereas potential geniuses have a significant element of unbalance, such that extreme abilities in one or more domains are not balanced by extreme abilities in other domains.
Therefore, in potential geniuses extreme high abilities are not held in check but are instead given free-rein.

This means that potential geniuses are all, more or less, unbalanced - at least by the standards of most people; and this unbalance can come out in terms of (more or less severe) psychotic symptoms (such as a tendency to hallucination, delusion, loose associations of thought, trance states), or psychopathy (selfishness, emotional coldness), or an impulsive and willful personality, or prone-ness to intoxication (as a cognitive self-manipulation), or extremely narrow interests, or a refusal or an inability to do what is required or expected...

There is no single pattern of unbalance - but I think it probable that all genuine P-Gs (and all true recognized geniuses) are qualitatively different from the norm as an intrinsic consequence of being unbalanced (unbalanced abilities being necessary to that creativity which makes them a recognized or potential genius).
They are all significantly oddballs in some way or another - eccentrics, mavericks, irritating, unreasonable, nutters, nasties... not team-players.
Recognized geniuses come from potential geniuses which come from those with specialized high abilities that are significantly un-checked and unbalanced; and such people are troublesome to have around, predict and control.
At any rate, the current ruling elite have implicitly decided to exclude such people from organized power - so while modern society has some potential geniuses, we have no actually recognized geniuses.
In particular, many of his observations about the nature of creativity and its treatment by modern society seem to relate quite well to aspects of the hacker archetype.
