I have a buddy that helped me out with some DIY/construction projects. He thinks he is a 10x as well since he gets so much done so quickly. He will finish up and sit down saying its done. I go look and every tool is literally everywhere, garbage and debris thrown about, and half the stuff is incorrectly installed as he didn't think he needed to read the instructions and missed key details.
You're fine no worries. I think you are making my point.
People who claim they are 10x'ers are often not. They are mess makers or wannabes. They appear 10x to those who do not take messes or tech debt into account.
You screaming (to use your lingo) that my buddy above is not a 10x is what the rest of us have been screaming about our co-workers!
I'm not claiming people can't be 10x'ers. Nor am I saying being good is actually bad.
