This happens with every language that reaches popularity. That’s because it’s typically easier for individuals to engineer solutions with tools they know well, even if suboptimal, than it is to become proficient with new ones that might or might not deliver better results in the end. No community is immune to this, even outside IT.
I’m pretty sure you’ll also occasionally bang nails for which Julia is a poor hammer, you just don’t realize it.
Oh I definitely know there are things Julia is not good at. It is just that Julia does not get in my way as frequently as many other languages.
But I kind of keep a collection of favorite languages under my belt which cover different areas. My favorites are probably Julia, Go, Swift, Python, Lua and LISP in that order.
If I need more low level style coding I would go with Go (pun not intended). Swift is nice if you want to actually want to make GUI applications and something that is quite robust. The type system in Swift is quite good at catching many problems.
