Your Job Is To Code

That sounds like advice from a relatively inexperienced developer. As a senior developer, product managers and my own management come to me to ask for my advice, not just to tell me what code to write. Having worked on the product for a number of years, I remember why we designed things a particular way, how previous attempts to do something failed, etc. If I see us headed down a path that seems to lead to a bad outcome for the company or its customers, it's my duty to the company to raise my concerns and try to improve the strategy.

The original article that's being responded to[1] says:

"Your job is to solve problems (and sometimes that involves coding)."

That seems to be a reasonable statement. If I can make a problem disappear by discovering a solution that doesn't require coding, why should I write code? If I can make a convincing case that the solution to a particular problem is better to implement in a different part of the product that somebody else is responsible for, it's my responsibility to do so.

The original article goes on to say:

"Knowing your way around technology, fixing organizations' problems using those skills, and being able to explain the benefits is a rare combination that makes you much more valuable than being just a technical expert. You can establish a bond with bosses and clients that few other specialists can..."

This is also true in my experience. Part of the job of a developer is dealing with non-technical people (managers, customers, etc.), and there are skills required for this that go beyond just being good at writing code.
