No, it can't write code like a Junior Zig engineer with 1 year of experience.

And they all undertrained, according to the papers.

And how long would it take you to debug AI generated code again and again?

This shouldn't be factored in unless you never debug your own code. At any rate, I don't know about OP but usually when I get an LLM to write out some code, I also have it write out the tests for it as well.
