The lack of generics and an enforced GC still makes me very intrigued of the Rust programming language as an option for many future use cases, especially as Rust used to have something comparable to the go-routines and channels in Go.

After I heard they are moving out green threads to the standard library [1], and also abandoning segmented stacks [2] (something I'm not as much knowledgeable about, but have understood it has implications for concurrency), I'm starting to wonder whether it ever will offer the same strength in terms of building concurrent multi-core programs, as in Go.

Would be cool to have some experts give their views on this, and elaborate a little on what the consequences of those decisions will be, especially compared to what we have in Golang.
