That's true from a performance perspective but, in building an agent in Go, I was thankful that I had extremely well-worn patterns to manage concurrency, backlogs, and backpressure given that most interactions will involve one or more transactions with a remote service that takes several seconds to respond.

(I think you can effectively write an agent in any language and I think Javascript is probably the most popular choice. Now, generating code, regardless of whether it's an agent or a CLI tool or a server --- there, I think Go and LLM have a particularly nice chemistry.)
