At what point do you stop learning new programming languages?

AI-assisted coding - not full-blown vibecoding, but having an AI agent generate code under close direction, supervision, and review - allows me to work competently in a bigger set of languages/frameworks than ever before. In particular, in the last year I've written quite a bit of Typescript and Python without ever having learned those languages properly. They're both close enough to Ruby - a language I do know well - that I can read the code and understand what it does; or ask the AI questions when I see a language idiom I don't know.

Maybe, given enough time, I'll accidentally learn some new languages this way!

I look forward to seeing the languages that come from people with the benefit of a few years of Rust deciding what works for them and what direction they would like to move.

Still waiting for something that is like JavaScript with optional typing, none of the autocasting that causes Wats, and parallel loops and map,filter,reduce, etc. Oh, and tuples, immutables, and a pony.
