Sure, but what I’m saying is that at a high level of abstraction scientific discoveries are similarly inevitable as well. I don’t think niche creations are a major difference since as you yourself stated “without him we'd just have something else and perhaps it would've been a bit later.”. The majority build on previous findings, often many scientists are working towards the same goals, and truth is truth, whether it be found through physical experimentation or fleshing out applied logic.

There's lots of history you can look at to see how this works. The same thing does get invented more than once, but sometimes there's different technologies that could each become dominant, and then there's a real first mover advantage.

In Russia, they don't really have highways. Everything is built around rail lines. In the Inca empire, they had highways, but highways with stairs because there was no widespread wheel usage (which itself might be down to limited available wagon pullers and rough terrain).
