There are certain cases when people are wrong. Allow me to let them illustrate:
What Mike is trying to say here: Using a few important thermodynamic principles, air conditioners are machines that move heat from one area to another. Typically, they move the heat from inside to outside.
This is ludicrous. He goes on to argue that we shouldn't set our thermometers. I mean, come on, doesn't the word set mean anything in our turbulet world? Yet, sadly, this is a consistent pattern. A phenomenon, if you will. We assume the world is 80% outside and we should simply give up. But have you ever heard the expression, something something the cold wind blows? Then you know what I'm talking about.
Thomas Munchine, before links were invented, proved definitively that lightbulbs do not emit light. They suck dark.
