That take might be overly cynical. People who have a jack-of-all-trades skill set might not necessarily build the best components themselves, but might be able to bring some big-picture insight that more specialized developers don't have the awareness for, leading the team in the right direction.

I'm not suggesting you transition into becoming a PM or Architect or anything like that, just saying that developers like you count, too. If you have a decent work ethic, then you and your unique brand of knowledge-seeking have something to bring to the table.
