Meh, that's a cop-out. "You don't need complex sentences to express complex ideas." and "They don't use more complex sentences, just different words"? It's pretending that the complexity in the language lives only in the grammar, and not the jargon. Think of it this way: if spoken language gets more informal in terms of sentence structure the harder the topic, that means that the easier the topic, the more complex the sentences. I think PG has confused the informality people have when they have a common understanding with something else. Do you really think that a pair of experienced mechanics in an auto shop discussing a basic repair are going to be using more formal language? Turn one of the mechanics into an apprentice and consider the same discussion.
