Great discussion! As someone who works with AI coding agents daily, my take is that the "best" language really depends on what the agent is building. Go's simplicity and predictability are huge for general-purpose agents, but I've found TypeScript shines for agents that live in the web ecosystem - interacting with APIs, browser automation, etc. The ecosystem alignment matters a lot. Python will always have a stranglehold on data/ML workloads simply because that's where the libraries are. The key insight might be: pick the language that matches your agent's domain, not just what the LLM generates best.
