You cannot have it both ways though. Either these are meaningful examples of Rust's benefits, or they are not worth mentioning. In a thread about Rust's concurrency advantages, these editors were cited as examples. "Don't block the UI thread" as justification only works if Rust actually provides something novel here. If it is just basic threading that every language has done for decades, it should not have been brought up as evidence in the first place. Plus if things like work-stealing queues and complex synchronization are not relevant to editors, then editors are a poor example for demonstrating Rust's concurrency story in the first place anyway.
