> I think a good Kotlin Native backend could be a great language in the Go space

With Ktor there is the beginnings of that. It can actually compile to native; but with some limitations. There's also the web assembly compiler which would make sense for things like server less and edge computing type use cases. Both are a bit neglected from a server side perspective by Jetbrains. But the potential is there. And the whole Kotlin native path could be a lot easier and more lightweight than dealing with Graal.

The weak spot for Kotlin native outside the IOS ecosystem is compiler maturity, the library ecosystem, and lack of support for system libraries (e.g. posix and WASI for wasm).

Those are fixable problems. But it's only partially there currently and I would not recommend it for that reason. However, I think the whole effort with IOS native has moved things forward quite a bit in the last two years. Getting Kotlin to the level of Go in terms of compilers, tools, performance, and libraries on Linux and wasm would be similar in scope. But a few years of focus on that could make a lot of difference. IMHO, Kotlin could be perfect as a system programming language with some effort.
