We already have enough happening in programming language. Hear me out, IRL we do occasionally try to learn new languages but we spend a lot of time learning new ideas, mental models and frameworks to accumulate and distribute the ideas.

This is akin to various frameworks/libraries/packages in programming world. A new programming language shall only come when something fundamental changes eg. languages to support multiple cores, going back to async as single cores become good enough, quantum computing is going to spin off new languages.
