A big part of programming is learning. You need to learn. It's not only about learning a programming language. Programming language is just a tool. What you need to learn is: 1. How to use that tool effectively 2. How to build better products with it. You are never done learning those. And the best way to learn is to (at least try) to build it yourself. Therefore I think it makes sense for programmers to try to build it.
