If all you need is a comprehensive suite of evals / unit tests to determine if something functions correctly, and AI can quickly figure out how to change it so you get to the end result, then... seems like we won't need all these programming languages.
I would think modern optimized binaries would be too complicated for current LLMs to handle. LLMs currently get overwhelmed with large code bases, imagine turning that all into binary.
