Thank you for the incredible answer!
I like the idea of Julia being the standard optimization software, the way statisticians frequently write an R package for a new estimator. Julia is also good for this because bad code in R is very slow, while bad code in Julia is often still okay. (statisticians aren’t great at writing code)
I haven’t been part of this whole world ecosystem very long (and still am not a contributor, learning), but am fascinated about how open source software can make money. Though I recently looked up Matlab and Mathematica’s revenues and was surprised.
Thanks for the response. Its cool learning about this community while I learn the language.
