The article discusses Ousterhout's Dichotomy, which highlights the trade-off between programming language usability and performance. It notes that while some languages like C++ produce fast code, they can be difficult to use, whereas languages like Python are user-friendly but slower. The author explores the idea of creating a universal language that balances convenience and performance, suggesting that previous attempts have not succeeded. High-level languages often struggle with performance due to their reliance on garbage collection and pointer-heavy object models, which can hinder the efficiency of low-level programming. Rust is presented as a potential solution, as it lacks heavy runtime features and maintains a consistent object model, allowing for both high-level usability and low-level performance. The article categorizes Rust usage into different levels of optimization, from "Sloppy Rust" to "Crazy here-be-dragons Rust," indicating that while Rust may not reach Python's usability, it offers a unique balance of performance and safety. The ability to incrementally optimize performance without extensive rewrites is highlighted as a significant advantage of Rust, making it appealing for developers who may not initially know the performance requirements of their projects.

Swift is a more convenient Rust
Swift and Rust are both functional programming languages with LLVM-based compilers, but Rust focuses on performance and memory management, while Swift emphasizes ease of use and developer productivity.
2 comments> Why are there so many programming languages? One of the driving reasons for this is that some languages tend to produce fast code, but are a bit of a pain to use (C++), while others are a breeze to write, but run somewhat slow (Python).
The only thing I learned was that there's a name for this. There's definitely more than 2, e.g. Lisps, Rust vs C++, and F# vs C#, etc. People think/work differently and use languages that work well for them.
