This is technically correct, but it's also true that if a group of dedicated Python enthusiasts (led by Travis Oliphant) hadn't created a Python ecosystem before they had users, we can say with certainty that Python would not have taken off in the numerical computing space. In 2005, when I was looking for a new language, I really wanted to use Python but it was simply not an option.
