You make a lot of assumptions that end up not playing out so well. For example when I was at university we didn't have a single core language we used for everything; classes bounced around between C#, Java, C++, Python, Ada, HTML, Javascript and so forth. There are graduates that have wide experience but not depth. Which speaking as an aside; I was denied an internship back in college because I didn't have three years of professional experience in Java. Needless to say I found it absurd at the time. You also assume that the best people are coding earlier or have the ability to code earlier. Some of the best developers I've worked with didn't start coding until later in their life.
