DevOps is partly about moving code from your editor to users. There are many things that can happen during this process. The main point is automation.

This means some people (DevOps engineers) write code / config systems to realize the process. Then, application developers can take greater ownership over the entire lifecycle of their software, so they end up in the ops side.

When done well, this benefits everyone.

Since software has to move, it is unlikely DevOps, as a practice, will go away.
