That will lead to one of two things: (1) information paralysis, where no-one authoritative is willing to speak in public for fear of making a mistake (and so the public sphere is ceded to the ignorant); or (2) constant churn, where experts are constantly removed from the public sphere (because everyone makes mistakes), and so we only hear from the people who haven't yet had enough experience to make a mistake.
