Pretty much everything in the enterprise. It simply should not exist. All that CRUD stuff (that should have been automated long ago, it does not deserve all the boilerplate), everything Java, everything that is going on now in the Web. It is all amazingly overengineered. Doing things in an idiomatic Lisp way would have resulted in 1/1000th volume of a code doing 10x more. And, of course, in 95% of the developers being redundant.
