"Mojo aims to combine the usability of a high-level programming language, specifically Python, with the performance of a system programming language such as C++, Rust, and Zig
Mojo builds on the Multi-Level Intermediate Representation (MLIR) compiler software framework, instead of directly on the lower level LLVM compiler framework like many languages such as Julia, Swift, C++, and Rust.[16][17]
MLIR is a newer compiler framework that allows Mojo to exploit higher level compiler passes unavailable in LLVM alone, and allows Mojo to compile down and target more than only central processing units (CPUs), including producing code that can run on graphics processing units (GPUs), Tensor Processing Units (TPUs), application-specific integrated circuits (ASICs) and other accelerators.
It can also often more effectively use certain types of CPU optimizations directly, like single instruction, multiple data (SIMD) with minor intervention by a developer, as occurs in many other languages"

Providing usability without GC is an oxymoron.
The best attempt so far for Pythonic compiled language is D, that's probably why it's not mentioned in the Wikipedia entry along side other languages comparison. D has GC by default but manual memory management is supported as well.
Probably compiler researchers need to come with truly determinstic GC like the automotive industry invented the automatic gear. So that other existing compiled programming languages with GC like Go and D can thrive.
