How Rust is quietly taking over the Python ecosystem

A February 2025 Reddit thread generated over 900 upvotes and extensive debate on r/Python. The original post noted that performance-critical Python tooling like the Ruff linter, Polars DataFrame library, and uv package manager are increasingly implemented in Rust, attributing their adoption to order-of-magnitude speed improvements. Commenters debated whether this constitutes Rust "taking over" or simply continuing Python's historical role as a glue language for C/C++ extensions, with many arguing Rust is primarily replacing C/C++ in this niche due to its memory safety and modern tooling. Concrete outcomes include the successful migration of high-profile projects like Pydantic v2 to a Rust core (pydantic-core) and the emergence of a commercial entity, Astral (creators of Ruff and uv), securing venture funding to develop these Rust-based tools. The discussion revealed significant community friction, with critics labeling Rust advocates as overly vocal and expressing concern about ecosystem lock-in and compile-time dependencies, while proponents highlighted tangible gains in developer experience and performance.

Reddit r/Python discussion (928 upvotes, 358 comments) reveals community skepticism toward framing Rust as 'taking over' Python ecosystem. While acknowledging tools like Ruff and uv, commenters argue Rust simply replaces C/C++ in Python's traditional architecture, not Python itself. Criticism focuses on Rust evangelism and perceived misunderstanding of Python's role as systems integration language. Notable tension between tool builders promoting Rust and Python pragmatists defending existing paradigm.
