Also, not everything runs on x86. For example, you couldn’t write a website in raw binary, because the browser wouldn’t run it. Or maybe you already have a Python library and you just need to interact with. Or maybe you want code that can run on x86 and ARM, without having to generate it twice.
As long as the output code has to interact with other code, raw binary won’t be useful.

I also expect that it might be easier for an LLM to generate typical code and have a solid and tested compiler turn it into binary
