I love ML types, but I've concluded they serve humans more than they do agents. I'm sure it affects the agent, maybe just not as much as other choices.

I've noticed real advantages of functional languages to agents, for disposable code. Which is great, cos we can leverage those without dictating the human's experience.

I think the correct way forward is to choose whatever language the humans on your team agree is most useful. For my personal projects, that means a beautiful language for the bits I'll be touching, and whatever gets the job done elsewhere.
