I watched a Rust intro video recently that provided a perspective I liked, so I’ll share that here: MS, Apple, Google (and more) all relied heavily on C for low level code that needed to be as performant as possible. It turned out though that C‘s memory management is so problematic that many/most security issues are caused by it. To address that, Google invented Go, Apple made Swift, Mozilla gave us Rust etc.

MS is interesting - they tried to write memory safe C and invested heavily, but admitted defeat eventually - and started using Rust. And I think that’s what will happen at most companies eventually. Rust has a lot going for it (faster than C sometimes, excellent WASM support etc). Swift might have been another contender, but Apple kept things too close to their chest for too long IMO.

As another poster wrote, Swift certainly won’t die at Apple (and their ecosystem), and Google will certainly keep Go alive. But I think Rust will eventually be used at many/most other companies for anything security or performance critical. Maybe it will replace C as the de facto low level language.
