I post this in response to the lack of a Julia tag for articles like this:
https://lobste.rs/search?order=newest&q=domain:julialang.org https://lobste.rs/s/l9nzb2/julia https://lobste.rs/s/4oiipw/why_i_m_betting_on_julia https://lobste.rs/s/vmdb9v/julia_language_for_scientific_computing
Julia has been proposed before, but I think the audience of this site for that sort of thing is pretty small. Except for the ai tag, there isn’t much on this site here relevant to the data scientist in general as ai is too-specific, and Julia is still pretty small compared to the visibility of major projects, but of some interest to the plt and lisp people here due to its relatively unique language features. I don’t think the differences between the languages and tools are significant enough to have separate tags for julia, scipy, R, matlab, and stata as of this point, and there is a great deal of overlap between users of Julia and Numerical/Scientific Python. In summary, julia seems to be too small of a community here to justify a specific tag just yet, but computational science is well-defined enough to warrant it. ai exists, but is a subset of data science. Computational science also includes modeling and simulation tools which might not fit under AI/Statistics, and is too far removed from compsci.
