Ask HN: Is it worth getting into distributed systems after 12 years full stack?

I have done 12 years Full Stack engineering, including some DevOps. Recently I have been getting very interested in Distributed Systems, and not just at a consuming level but at the theory level. I would like to get into the gritty details of distributed systems, perhaps to the level of a Masters' Degree.

Is it worth getting into the the subject? It would take a major commitment in time and efforts. Would it help with better career opportunities?
