  Won't work for any of the languages mentioned. Somewhere underneath it all you need a runtime witten in a bare metal language

    Rust, Go, Lisp do have certainly bootstraped compilers, with the runtime also written with them. For Python and Ruby, it is a matter of someone actually taking the effort of doing it, which no one does because it would only be proving a point that anyone with major in compiler design already knows it is possible, just with lots of hard work.

    Source of your claim? Lisp compilers have been written in Lisp for the last 30 years or so. I don't care about Ruby or Python, both toy languages.
