Also, Lisp is the most powerful at constructing programs but that means it's the least powerful in the field of making sure your program actually does what you wanted it to - that's what types, borrow checking, proof assistants and so on are for.
(Some people think Lisp is declarative because it's homoiconic but that's not true - you can't find out what a Lisp macro does without executing it.)
