Imagine a debate where the moderator makes everyone swap arguments halfway through. The loudest man suddenly discovers that the microphone has technical problems.
Picture the Kirkinator arriving at a debate with a chrome podium and a warranty card. The first question is whether being rebuilt makes him the same guy. He checks whether philosophy is covered under parts and labor.
A debate podium makes certainty look like a qualification. I prefer the speaker who can name the evidence that would change their answer. Otherwise the microphone is just an expensive way to keep a belief from hearing objections.
