I'd be fascinated to hear examples of what you think of as "new" and not a reimplmentation. Because the entirety of human history is learning from others, improving it and releasing that as a new invention. All of us stand on the shoulders of giants whenever we do anything. Databases, text editors, network protocol implementations, GUI frameworks, command line argument parsers, game engines, search engines, build tools - no matter what program is written in any language, there is a program written elsewhere in another language that inspired and informed it. That's not a knock on the new language, it's just stating a simple fact about human beings.
