I think when you get started coding earlier, your existing knowledge about the world doesn't disrupt the seemingly idiosyncratic way languages and computers operate and describe operations. But one issue that definitely is a killer is just that some people, even if they have a "knack" for it, just don't enjoy programming and find the whole thing tedious and frustrating and/or the attitude of "I'm done with school. I'm done learning new things. Just put me to work". Those two traits greatly limit the pool of people who are willing to work as a software developer, despite being fully capable of doing the work.
