> Java, Go and Rust can run programs at native speeds on non-x86-64 architectures, e.g. ARM, but Cosmopolitan cannot

These things are not mutually exclusive. Nothing is stopping you from shipping a JVM, Go, or Rust app ontop of Cosmopolitan.

Actually Cosmopolitan doesn't support threads so Java, Go and Rust won't work at all on top of it. https://github.com/jart/cosmopolitan/blob/master/libc/runtim...

That's not the claim though. The claim is that Cosmopolitan offers the same portability benefits as Java, Go and Rust, not that Cosmopolitan + (Java, Go, Rust) offers the same portability benefits as (Java, Go, Rust).

Also the latter claim is not true AFAIK. For example if Cosmopolitan were to support all the architectures Rust supports, at native speeds, it would have to support packaging the compiled code for those different architectures into some kind of super-fat-binary. Currently it only supports x86-64.
