I think this myth comes about because early in peoples' careers, the expectations of the job are a lot more focused on writing code to execute a vision defined by someone else. It is easy to get the impression from this that writing code is viewed as the most important part of the job. But in reality, it works this way because the opposite is actually true, the more important non-coding parts of the job are being entrusted to more experienced people (often to their chagrin, because writing code is way more satisfying and fun).
