If there are some out there who truly are of unparalleled execution ability, focus on testing, testability, reusability, modularization, componentization and simultaneously lifting up the team, I've never met one in my years in the industry. I don't think even if you spent 100 hours a week, you could achieve all of these things at once, so you have to compromise somewhere, and I know where people usually compromise. And that's before factoring in work-life balance haha.
In the early days of your company sometimes you do need people to just bang shit out, and eventually, you'll pay 10 1X engineers to clean it up. That period in a company's lifecycle is limited and the 10X'ers are outgrown very fast. Often they don't understand why but to their peers it's painfully obvious.
