Speaking is dangerous. Speaking creates an illusion of necessity, of power, of control. They're given an honorarium, private housing, and all expenses paid. Fame is always dangerous. Fame is always destructive.
Fame seduces speakers into believing their own press releases.
Speaking contaminates every speaker. And there are no exceptions. No speaker leaves the world of speakers unscathed. In fact, the only way a speaker can escape the negative consequences of speaking is to stop speaking. There's no other way.
