They weren't just playing with Rust on the side anymore they were using it to produce professional code for other people to run. In 2021, for the first time, more than half of all Rust programmers were using the language on the job. Rust's core team runs a developer survey each year. Rust turns all the deep theoretical thinking about the best ways to create systems into a living, breathing, useful language.
Building these systems is challenging enough, and squeezing the bugs out of them is even harder. It’s aimed at helping systems programmers and others who want to create code that juggles dozens, thousands, or even millions of events simultaneously. Rust is one of the few newer languages to find a home in the field, where developers write code that runs in production for real enterprises. It's rare for a new programming language to break out into the big leagues and be widely used.
Many end up being niche languages, best used to scratch an itch or fix a particular issue. A programmer gets a flash of genius and sets out to create something fresh and wonderful. It seems a new programming language is invented every day-certainly more languages than most software developers will ever need.
