Why would they been seen as a "eternal beginner" by anyone? Learning a language for 1-2 years and then working with it, while having general programming language for 10-20 years would come anywhere near "beginner" for me and many I know. Once you've picked up one and mastered one object-oriented language, most of them mostly look the same, and same goes for the other paradigms. A lot of knowledge transfer between languages, so if they see you as a beginner after 20+ years of experience, their loss.
