Rust is a language for building foundational software. - https://smallcultfollowing.com/babysteps/blog/2025/03/10/rust-2025-intro/

What all clients have in common, however, is that the services they build with Rust are foundational to their core business. Rust is used for building platforms: systems which enable building other systems on top.

This mindset takes away the focus from Rust as a C++ replacement and also explains why so many teams which use languages like Python, TypeScript, and Kotlin are attracted to Rust.

What is less often talked about is that Rust is a language that enables people to move across domain boundaries: from embedded to cloud, from data science to developer tooling.

Rust serves as a catalyst: companies start using it for critical software but then, as they get more comfortable with the language, expand into using it in other areas of their business.
