If lisps are that good why there's so little killer software written in it?

With rare exceptions like emacs and clojure's datomic I feel like such a lauded language should have more to show.

And yet, there's comparatively much more killer applications written in php alone than all lisps combined.

I am proficient in several lisps by the way (Racket, CL, Emacs Lisp, Scheme) and honestly every time I need to start a "serious" project I just feel like any other language depending on the use case is a better fit.
