I expect there are many careers that are similar. In some ways, your experience doesn't matter. A civil engineer with 40 years of experience building houses, malls, or parking garages is still a rookie if they're building their first bridge, right? Many concepts still apply, maybe even most, but it's still going to be new and difficult. I have over 30 years experience as a software developer but I wouldn't want to program for medical equipment or dive into complex low-level architecture that I haven't thought about since college.
