When you communicate in text you can just sell the idea you're talking about. When you do public speaking you have to sell yourself AND the idea (in this order, because nobody will pay attention to the idea if they are not alresdy paying attention to you). So good public speaking will always have a "cult-ish vibe". And unfortunately, with current declining attention spans and younger generations preference for video over text we'll have to get used to this annoying media and its side effects. Even people learning programming want "video tutorials" and "code-casts" nowadays...
