I think it’s more fair to say R and matlab are domain specific language for scientific computing as the core of the languages makes assumptions about your data

I think it’s more fair to say R and matlab are domain specific language for scientific computing as the core of the languages makes assumptions about your data structures (you can only have vectors and matrices. There are no scalars - only arrays of scalars) Julia’s community focus on scientific computing, but I’m sure in five years time, nobody is gonna bat an eye when a Julia ship do their infrastructure scripting in Julia (while we’ll still bat an eye at R shops doing that in R)
