Khan academy is a wonderful resource and for free. People falling for this utter bullshit is directly attributable to one word. Marketting.
Khan Academy is a golden standard, which these guys can't ever aspire to become.
the same bs. asking children over the top questions then showing them pretty animations and promising the stars.
this whitehat is another level of disgusting.
i have relatives who i have been slowly teaching scratch, arduino, even a 3 year old who does gcompris and they can now use a computer. will that give them a job? absolutely not. will it help them get a tiny bit interested in computers? yes most definitely.
