If you watch Myth-Busters you find that even amateurs can fake a YT video and make it look real. You Tube has taught me that video clips are not necessarily honest. About the same as mainstream news these days.
Youtube taught me a lot like when i have something to know about how to solve my cellphone's problem, youtube answers me through the links that i clicked and watched. It just depends as to what you really need. If it is just for pleasure then you can enjoy playing with the music, and if you want something informative, youtube still has its best to show!
That video does not point out that the economics profession does not subtract the depreciation of all of that consumer junk but it was all added to GDP when it was sold. Running a planet of 7 billion people on defective algebra. Economists are so brilliant.
