At some point you will hit diminishing return. That's a good time to start exploring other endeavors and add to your skillset. It's not that specialization is junk or good, it is that we get complacent. For example, I dabbled with programming and computery stuff all my life. I like to think I am pretty good myself. It is not until a few years ago that I started taking improv classes, a form of theater that I began finding something else that I am really good at. Today, I continue to deepen my technical expertise. Not so much in programming, but in electronics, 3D printing, and CAD. However, I will eventually return to programming to expand my skillset there. In the performing art, I am pursuing voice acting. There's paying works in voiceacting for sure. Even improv has potential for paying work if I bother to teach a class or coach a team. Money isn't why I pursue these disciplines. I found that I am getting stagnant in my acting skill, so I decided to do something new. Specialization isn't a bad thing, but it pays to continually expand your skill in both breadth and depth. Not just learn the 15th new framework hotness or wahtever. It might even pay to do something that could be the furthest away from your expertise.
