Technically, of course they are all encodings of the same thing (and can be transpiled into each other). The domain specific languages (DSL) crowd seeks to find the optimal encoding for a given problem. Sometimes this is quite blatant e.g. Go is essentially a DSL for webservers. The Racket heads (PLT) focus a fair bit of effort on this, but I'm not sure if it's really a productive/fruitful development paradigm (although the book Beautiful Racket is lovely, and SICP through the compiler building etc. clearly implies the same direction.) On the other hand, Python etc. are just c wrappers!
