If Lisp was so good...

Can you name one GREAT work of programming done in Lisp?

You can't.Even AI developers have abandoned LISP

Programmers who learn C, C++, and Java are doing it to produce something useful.  Programmers who learn Lisp are doing it to learn Lisp.  It sucks up programmer time an effort to obliterate it out of existence at the centre of the singularity.
