Can you elaborate on how you envision things like hacker school to solve the problem of stars, if those can't be trained? I am not trying to be semantically nit-picky - I don't think I understand how star programmers come about, and maybe you have better insight.
The only thing I can think of is that you might imply that being a star programmer is an innate talent that needs to be developed, and things like hacker school would allow for this talent to be discovered. Is that about right?
