My company decided to used Julia as a general purpose language for a number of projects around 2.5-1.5 years ago (I’ve been there 18 months). I firmly believe this choice had an opportunity cost somewhere in the 1-2M $ range for a sub 25 person company. The number of bugs in the language, which had no doubt since improved, and the lack of libraries, which leads to serious NIH (b/c really it’s just NI yet) was costly, and frankly dangerous in the context of security, and then generally with regards to reproducibility. At one point we had a tool which leaned heavily on macros and required a version of the language which no one no longer had on heir machine and had no download links on the internet anywhere. Luckily they are consistent in their version uploads and altering the download address to have that version happened to line up with what’s in their server, but running a company in something like that is tenuous at best.
