These articles keep coming up, and the author never actually tries agentic coding in Rust vs Python. You will probably find that the LLM does better with Python for kinda similar reasons as humans. It's succinct and can be rerun quickly while you iterate. There's also the difference in training data. If/when a human needs to review code or intervene, same applies.

Can't say I've tried Rust, but my AI tooling has always been noticeably worse at doing comparable tasks in C++ instead of Python. Not just toy examples but real systems in prod with testing, maintenance, oncall, feature rollouts, etc.
