Not OP, but all the choices made along the way are the human part. The understanding and creativity to solve the complex challenges that arise in an efficient way that fits into the structure of the greater program.

Programming never has had one right way to accomplish a task, and that is disappearing with agents. Why would pick Ruby for a project because it’s nice for the programmer, when the agent is the one coding? In fact, Why would anyone ask an LLM to write a new program in almost anything other than JavaScript and Rust?
