It's becoming so evident now that Rust is going to sweep the systems programming space at the expense of just about everything else--and perhaps not only systems programming... Coders I know who worked the previous decade with Python, Ruby, or TypeScript have over the past quarter switched to vibecoding Rust. Why not? Faster, safer, smaller (memory-wise), simpler (deployment-wise), what's not to like? Similarly, Rust is eating the Python ecosystem from the inside outwards (uv, Ruff, Polars, Pydantic, etc, etc) Rust is an emerging Schelling point for coding agents. Its infamously strict static constraints function like guide rails, such that by the time the code actually compiles, the job's often largely done. And Rust's best-in-class, precise compiler error messages (valuable when compile cycles are slow) help agents make quick work of pinpointing & troubleshooting the effects of their changes We didn't yet see this sweep prior to this year because models were simply not capable enough of fully mastering the nontrivial complexity of the language (cf. ownership). They still made mistakes that I now simply no longer see with the current frontier. Rust seems to have a particularly pronounced threshold effect: the same strictness that repeatedly blocked a weaker model now actually helps the stronger model converge! For my own work, Fable 5 was the inflection point where the quality of generated code often exceeded what would be economical to code manually. (Astra and Opus now mostly do okay, too) This new Rust hegemony will become obvious to everyone during 2027, with much gnashing of teeth!
