The whole point of a Summary video of history, and what is tested in class for most students, is the what and when - not the who and why.

Also, from reading the original scare-mongering article based on a single video viewed by the author, i didn't get the feeling that he was complaining about the lack of 'who and why' but rather libruls like Khan and Gates are taking over the world and throws in a irrelevant point about personalization engines in google and facebook.
