Yeah, there’s some variance, but I’d argue it’s actually pretty small. I’m trying to figure out who I’d choose, but it’s hard, because usually there’s a lot of redundancy even when it comes to kings and generals, and nothings lasts more than a couple centuries or so on pure momentum. When archeologists excavate a place like Rome, without writing it’s hard to even distinguish leaders. Rather, you can see trends smoothly changing over time, usually in response to something obvious like supply chain issues.
You can also see this if you look at the stories of today’s great successes, and then compare them to the stories of people they would have started alongside. There was a lot of online stores in 2000, and one was bound to become Amazon. Amazon itself apparently was the first to allow negative book reviews on it’s storefront, and that helped it through the lean years. That meeting could easily have gone a different way, and then it would have been someone else.
