I was sold this same line since I started my career in software as an intern ~15 years ago. Every year I've become less convinced that fully applying myself is worth it for my career. Any time that I've stepped up to fill a gap when it didn't directly benefit the short-term perception of my manager/skip-level, the effort was undersold or outright ignored.

Edit: ok - I'll admit, I didn't read the whole article at first. I still stand by my point, though - even when I'm simply identifying those gaps and not fixing them, I still don't see engineers being rewarded proportionally for the value they're bringing their employers.
