1.8 million views for an old codger giving a lecture about arithmetic? What's going on? You'll just have to watch to see what's so damn amazing about what he (Albert Bartlett) has to say.
I introduce this video to my students as "Perhaps the most boring video you'll ever see, and definitely the most important." But then again, after watching it most said that if you followed along with what the presenter (a professor emeritus of Physics at Univ of Colorado-Boulder) is saying, it's quite easy to pay attention, because it is so damn compelling.
