how many times in history does this need to be disproven? some of the most insufferable assholes in human history were absolutely brilliant once-in-an-era types.
it's a chicken-or-egg question to ask whether or not the brilliance comes from the confidence or the other way around, but opinionated assholes that can't operate in traditional team settings have a proven track record of effectiveness in the world.
the trick isn't to ignore the brilliance, the trick is to find a handler or method that works to smooth the burden so that your organization can take advantage of the brilliance without self-destructing.
in fact, here's a rule of thumb. if any opinion anyone ever concludes with "Let's disconnect this human from society until they fix themselves" , well , I humbly disagree.
