I think his problem of persona mis-matches is a temporary problem we all will face. Are you a leader of your organization or are you a burning man guy? We all have limited time to understand your true personality, so we have to rely on our best generalizations and stereotypes.

However, not too long from now we will all either be a) so exposed that our simple notions of persona will break down. We can just be people and we can be judged in context instead of these pseudo-personas, or b) we will all be so scared about breaking our personas that we will just withdraw from expressing ourselves honestly.

In the meantime, yea its a broken system. If you want to express the persona of a successful business person, it might just mean you don't get to express yourself as burning man dude until you retire or something. Its a sacrifice because the rest of the world just is not ready to see you as both.
