Will we ever even get a widespread new programming language? AIs work great for coding because they have massive codebases in C/C++/Python/JS/etc. to train on. If I create a language called "foo" tomorrow, no such codebase will exist for it and the lack of AI support for the language will be a huge barrier for adoption so it's going to be much less likely to catch on like Python did back in the day.

I'm working on my own lisp. I've used ChatGPT to generate some cases for my test suite. Somehow it can generate decent code if I instruct it thoroughly enough and provide samples. Maybe the fact all lisps have similar syntax helps?
