Its abstractions and memory safety aren't zero cost though. I do wish ffi between rust and c++ was easier, having just fought that battle again recently, but I'm not willing to give up performance over it.

I think it is telling that carbon came out of google, and rust came out of mozilla, but rust is what google is using to make android safer, and to create things like kataos.

kataos is a greenfield project. Carbon isn't being created for greenfield applications, it's being created to deal with maintenance of large existing c++ projects. The carbon repo publicly mentions that you are better off using rust otherwise.

Using rust in android is indeed interesting, but it's largely not hindered by legacy interop with c++ there either. Rust has struggled to overcome the challenges with c++ interop in chrome. I fear other c++ codebases face this same struggle.

That makes a lot of sense. It is hard enough on small codebases. I'm very familiar with some c++98 behemoths and I can't think of any good ways to go about it piecemeal. The interop truly is painful.
