> But why companies keep trying to push new languages to massive adoption. How many languages has this happened with and how often? Go, Rust, Kotlin, Swift, Julia, Typescript are in a generation of newer programming languages and they're between almost 12 (Go) and 7 (Swift) years old . Each of them offers something new in comparison to its predecessors. Almost every other commonly used language is from the 80s or 90s. There are other, more niche languages but they fall under your point about research, experimentation, doing stuff for fun etc. Just because some language pops up in blog posts or on HN every once in a while, that doesn't mean that it has wide enough adoption. Is any of this really that much? I don't think that learning a new language once every few years should be something that challenging especially for an experienced developer.
