LISP always makes me sad. It's a language from which all modern languages could learn so much (and currently a lot of features of LISP get cloned). LISP Machines pioneered basically 90% of what modern computers and the internet do today.
Yet, it's a very niche language, an almost forgotten artifact of time.
Clojure for me is the perfect modern LISP, too bad it seems it's dying (happy to stand corrected there)
There should be a Clojure based on C or Rust or a Clojure without garbage collection. High performance backend just can't be done in Clojure.
Take a look at Carp https://github.com/carp-lang/Carp
