Different programming languages have different qualities. For some tasks I like Ruby because it doesn't get in my way. But Ruby is built in C and so are JS VMs and web browsers etc (C/C++/Rust). A good LLM can convert Ruby code to Rust for a 10-100x performance boost, only multiplying the number of lines of code by 2. That makes Ruby a good programming language and Rust a good target language.
