For me, the strongest reason to use Rust anyway is that Rust makes it practical to write a single library that can be efficiently embedded in multiple runtime environments. One probably wouldn't want to use a Go library, for example, in a C, Java, or Python project, even though it's possible with cgo. Of course, if a Rust library is using async under the hood, it'll probably run a main loop on its own thread. But that happens often enough in C and C++ libraries as well.
