Swift concurrency

"Swift is an underrated choice for a compiled / systems programming language on Linux and other non-Apple platforms. It was fairly explicitly designed as a language that works with existing libraries/frameworks that expose C (or Objective-C) ABIs, but is significantly safer to write, but also has a tractable learning curve for the average busy programmer trying to get something shipped."

When it was introduced I was critical, but all that is true for Ada too, which has a very mature ecosystem, and in retrospect it is a tragedy that it was never used outside a few sectors. Rust and Go and Swift etc. are interesting, but if there had been a substantial switch to Ada instead of C++ so many current programming issues would simply not happen. Surely there were other languages of which many of the same things could be said, but Ada had the advantage of having a solid core user and developer base over most of them.

Actually it is not too late to start using Ada, which is a lot more familiar to average programmers than Rust. BTW I think that most Rust sources I have seen and written by Rust experts are written in a too-clever non-Rusty but Java-ish style, which is sad.
