As a general observation, dumping a video in the middle of a thread and expecting people to watch it is lazy. If you’re not prepared to take the time to explain what you got out of it, and why you think the points raised are reasonable, you shouldn’t expect anyone else to take the time to look at it. If you think the content is worthwhile, it’s your responsibility to highlight the aspects of it you think make it so; otherwise discussion devolves into a war of attrition where whoever has the most free time to watch random videos wins—and that person will pretty much always be unhinged.
