I said in my post I have and continue to make those calculations. You can’t be successful in any endeavor without. But notice I said the ratio is wrong. It’s not 10/90, it’s 90/10.

I also said if the goal is to rebuild twitters culture in a different mold then this is a way to do it. But it is not about identifying the 10%, it’s about identifying the people who map to the intended culture. That’s fine too. But they are driving away the force multipliers by doing this, and creating a reputation that will drive them away. That’s because force multipliers necessarily love the people individually they work with. They aren’t making the cold calculations you’re talking about, and they are generally repulsed by them. And you can’t have an excellent engineering culture based on mercenaries.

You don’t have to believe me. This is just my observations after decades of being involved in these things directly and being the one making the cold calculations.
