And I wouldn't overestimate a language's popularity. It's mostly a social phenomenon and rarely has anything to do with technical prowess.

I agree that integration with the separate LLMs / agents can and does accelerate initial development. But once you write the integration tooling in your language of choice -- likely a few weeks worth of work -- then it will all come down to competing on good orchestration.

Your parent poster is right: languages like Erlang / Elixir or Golang (or maybe Rust as well) are better-equipped.
