And yet all your comments have been on the reactions to the video, and not about the video itself. Physician, heal thyself!
The reality is that the video is not very interesting, really. The content is well known around here, and even simplified explanations have been done before. There's nothing much to say about it.
HackerNews is very sensitive when it comes to sexism, but not so much when it comes to H1Bs or outsourcing or China.
It's embarrassing that the purpose of the video is overlooked for PC.
