The problem is, the landing page says it's "similar to Java" right in the first sentence and in the second sentence "same portability benefits as high-level languages like Go and Rust", and later on "excellent performance on modern desktops and servers" and "compared with glibc, you should expect Cosmopolitan to be almost as fast".
The tricky part is, those claims are all true, they're just not all true at the same time. The portability claims are true (only if you ignore performance), the performance claims are true (only if you're on x86-64).
