alt Hacker News> And someone who isn't interested in sharing productivity gains with coworkers is basically engaged in sabotage.
Who says they aren't interested in sharing? To give a less emotionally charged example: I think my specific use pattern of Git makes me (a bit) more productive. And I'm happy to chew anyone's ear off about it who's willing to listen.
But the willingness and ability of my coworkers to engage in git-related lectures, while greater than zero, is very definitely finite.
Something that is advertised as 10x improvement in productivity isn't like your personal preferences for git or a few dinky bash aliases or whatever. It's more like a secret personal project test-suite, or a whole data pipeline you're keeping private while everyone else is laboriously doing things manually.
Assuming 10x is real, then again the question: why would anyone do that? The only answers I can come up with are that they cannot share it (incompetence) or that they don't want to (sabotage). You're saying the third option is.. people just like working 8 hours while this guy works 1? Seems unlikely. Even if that's not sabotaging coworkers it's still sabotaging the business
