Maybe this comment was too sarcastic but the core point stands. Julia’s main advantages for most ML and Data Science users are still theoretical. The package ecosystem is still way to immature. It’s not just MLJ. I was excited about Julia and made a good faith effort to port a work project to Flux and Zygkte and it was a disaster. There’s nothing wrong with passionate open source tinkerers working to improve the ecosystem, but don’t advertise it as ready for production when it’s not.
