Time and “order” are very unimportant with discoveries.

Im pretty sure historians would disagree with this statement.

I think time is an important variable, I should have stressed it more in the question. Sure, we would eventually get to the same ideas, but how long would it take? I suspect some development are somewhat expected as multiple people are simultaneously looking at the same underlying problem, while others come as a little more surprising.

It is very simple and few people, but it does work.
