Also, arguably, Julia, while fantastic, just didn't do that much that Python didn't do already. It's main argument outside of tidier ergonomics was basically "speed without leaving Julia" but with Numpy and Pandas being essentially stdlib, that just wasn't a very powerful argument. Julia was basically too incremental to be worth switching to. It seems to have found its niche elsewhere though with the optimization people?
Anyway, I see data scientists and statisticians (at least 100% of the ones I know) completely ignoring Julia, just because they only have been exposed to Python and R in their education. The quality of the programming language/ecosystem seems to be irrelevant.
Come chat in the Julia slack #finance or #actuarial channels!
