Mojo – a new programming language for AI developers
There are a bunch of questions about Julia, so I'll do my best to give a short answer to a very long and complicated topic.  Up front, Julia is a wonderful language and a wonderful community, I am a super fan.That said, Mojo is a completely different thing.  It is aligned with the Python community to solve specific problems outlined here:
https://docs.modular.com/mojo/why-mojo.htmlMojo also has a bunch of technical advancements compared to Julia by virtue of it being a much newer development and being able to learn from it (and Swift and Rust, and C++ and many many other languages).  Including things like ownership and no GC.  We also think there is room for a new language that is easier to deploy, scales down to small envelopes, works directly with the full Python ecosystem, is designed for ML and for MLIR from first principles, etc.Julia is far more mature and advanced in many ways.  Many folks have and will continue to push Julia forward and we wish them the best, it is a lovely ecosystem and language.  There is room for more than one thing! :)EDIT: Just in case there is any confusion, I work for Modular, built LLVM, Swift, Clang, MLIR and a variety of other things.  I wasn't trying to misrepresent as being unaffiliated.
