Mojo is a new language, a superset of Python, with a toolset for optimizing performance.
In particular it is intended to speed up AI/ML payloads, on diverse computing hardware.
Rust is a relatively new language designed to provide performance of C++ with safety.
The interesting part is that both of those languages are using same LLVM compiler platform created by creator of Mojo language, Chris Lattner. So at least "in theory" it is possible that Mojo could end up with comparable, or better performance, with very readable and relatively easy to learn syntax of Python.
With a great team, and $100M funded startup, that is very promising.
100x benchmark improvements over Python, and a 50% improvement over the fastest implementation in Rust.A look at the Mojo language for bioinformatics
