I know more than a few Computer Science majors who are much smarter than me (I didn't do CS) and know their stuff down cold but couldn't program their way out of a paper bag.
Maybe Sal can - dude can do pretty much everything else - so he almost certainly can do those videos, but there's still a distinction there, between the two.
Oh, sorry, I was ambiguous: I mean he has a BS in engineering and computer science. He's currently doing some casts on number theory, so he might very well already be on his way to touch on general computer science.
I think your suggestions are only going to be a part of the Academy far away in the future when all the basics are in order. When you watch a video, you usually have the necessary prerequisite knowledge for the material available as other Khan Academy videos. I think Khan approaches computer science the same way.
