This kind of comment is exactly what Rust skeptics are talking about when they are referring to the toxic Rust community.

I wonder how ChatGPT3 would respond to this?

If they crawled /r/programming and hackernews, it should be annoyed and come up with something along the lines of "fork it and write in in Rust yourself", "C++ has lots of inertia", "his main stack is C/C++", etc

While there is no pure rust model yet, there is a crate with bindings to the cpp model (probably not to this one).
