C++ is one of the fastest languages to compile*, assuming you aren't doing silly stuff like abusing templates. It just gets a bad rep because actual, real-world, massive projects are written in C++. Like, yeah, no wonder Chromium build times aren't spectacular, but I assure you that they'd be much, much worse if it was written in Rust. Pointing and scoffing at it when there's nothing written in Rust that we can even compare it to is just intellectually dishonest.

* It's not beating interpreted languages any time soon, but that's not really a fair comparison.
