"90% of what is being said takes 5% brainpower to process while the remaining 10% takes 300% of available brainpower." I'd argue that's the result of poor communication, not any deficiency in human speech generally. Granted, it's very very hard to construct something with the right level of addressable information at every moment. But when it's done right it is glorious. I think one of the things people implicitly recognize in good communicators (not necessarily good orators, but good communicators) is their ability to tailor what they're saying in this way.
