They mentioned Sarah Silverman's TED talk deflating the pomposity of TED, but it is unbelievable that they didn't mention the TEDx talk "2070 Paradigm Shift". A guy made up a completely false story about himself to get on a TEDx roster, then for 20 minutes made up complete nonsense like going to Rwanda with Elon Musk to give African villages ipads so they could learn javascript.
TEDx conferences are run by people peripherally related to TED, if at all, and they have a long and unfortunate history of giving a platform to frauds, hoaxes, and charlatans. I think it's gotten a bit better after some particularly bad talks came to light in late 2012, but quality control is still frequently lacking.
Strangely, this guy does not even promote his book. His book completely changed my mental approach to language learning. I highly recommend it to anyone who is learning a language.
