That again is a false assumption. I have professors who are great theorists but can't use a computer very well. It doesn't take computer savvy to be able to do

That again is a false assumption. I have professors who are great theorists but can't use a computer very well. It doesn't take computer savvy to be able to do computer science well. Hence my statement that you are confusing computer science and computer programming. The tutorials you see online are for practical applications. What you're seeing isn't computer science at all. Just a byproduct of it.
