> You don't have to worry about keeping your current job Depends on the job. There are employers who recognize the value of somebody who has broad experience, and who can/will do things that are necessary but not fun. There are also employers who only measure hands-on-coding skills, and/or who insist that everyone should be on a "growth path" even if they're already at a higher level than most will reach. Good people don't have to worry at the first kind, and very much have to worry at the second.
