Such a weird take on HN. Lisp should be experimented with if only to appreciate the profound beauty of a small, powerful, cohesive design. It is a wholly different feeling from industry standard languages which are constantly changing.
In Lisp, almost all of the language’s power is in “user space.”
The ramifications for that are deep and your beliefs as to whether that is good are largely shaped by whether you believe computation is better handled by large groups of people (thus, languages should restrict users) or smaller groups of people (thus, languages should empower users).
