I don't want to knock Lisp, or any other exotic language choices. They have their benefits, people have built successful things with them, and learning a different way of doing things can expand your thinking as a developer.
On the other hand, most of the world's most complex systems are built in boring choices like C, C++, Java, or Python. The claim that this or that can only have been built or get to market fast enough if it's in Lisp doesn't pass the smell test for me.
