Personally I moved from typed functional languages to Clojurescript and then Clojure around 10 years ago

Most serious Clojure code bases I'm aware of invest heavily in their test suite so yes you can just add a skill to your AI that tells it the most effective way to use your test suite then send it to the races

Some of my colleagues let the agent interact with the REPL and they report faster performance because the agent is not paying the start up cost on every interaction, personally I've been lazy there its fast enough for me

As you've hinted at Clojure does have less bits that get in the way, everything is true except false and nil, the language does not have order precedence table the core language supports immutable and persistent data structures as default

Everything is an expression nothing is a mixture of operators and expressions map, reduce, filter are built in and expected in normal code

Code you wrote 10 years ago in Clojure will likely still work today the ecosystem and language authors treat breaking code as taboo

Of all the languages I've used its the least headache inducing and the most freeing in terms of expressing my ideas

Also the defacto reverse debugger Flowstorm is a programming dream

Its a lovely language if you want to be content

The flip side of that is most users take it for granted and don't talk about it much

There are also a lot of commercial Clojure programmers who do not understand the language and as a result not that happy, they often didn't willing choose it, probably not ready for it, I think most Clojurians should have gone through a decade of noticing things in their other languages they didn't like before using it

Rich Hickey the creator of Clojure does famously influential videos on software but that doesn't mean your colleagues have watched them or care
