Makes sense. But regardless, the core language is better than go in almost every way (as far as I know)... and it has python like syntax. I wonder if thats enough.
I personally think Julia is technologically superior to a number of popular languages, with a voracious appetite for even more smarts. But you are right that this isn't necessarily enough.
Based on what I've seen so far, I think Julia could eventually break into the Tiobe top 20 languages (it's currently in the top 100). On the other hand, I think this is plenty. As a language currently aimed at (admittedly fairly large) niches that would be an outstanding outcome.
It also makes it fun to work with as a language. It's not just more chicken.
