I think as part to remain marketable in current technical job market, developers need to keep updating thier technical skills ..whether it is some CI/CD pipeline, cloud computing, devops or completely new language like Rust or Golang. Sometimes it can be quite distasteful and uncomfortable since we are swept outside our comfort zone.
