Sounds like everyone's got some main character syndrome, the cure for that is to be a meaningless cog in the enterprise wheels for a while. But then I suspect a lot of open source contributions are done exactly by those people - they don't really matter in their day job, but in open source they can Make A Difference.
Of course, the vast majority of OS work is the same cog-in-a-machine work, and with low effort AI assisted contributions, the non-hero-coding work becomes more prevalent than ever.
