> If you draw the distinction between Julia the language and Julia the ecosystem
Language and ecosystem are so intertwined that I almost never do this. Maybe when there are multiple well developed ecosystems, but when there’s only one, then it and the language are inseparable to me (for any language, not just Julia).
I remember Julia being pitched as a competitor especially for Matlab, but also R,... much more so do than for C or Lisp. So it seems like a fair comparison, and those are definitely to some extent seen as identical with their package ecosystem (in Matlab, most packages actually come from the same vendor, and base R utility is a tiny fraction of the utility of its packages).
