I'd say Lisp still has a decided advantage at greenfields programming of new stuff. Especially if the syntax & internal API requirements aren't completely clear yet, then the programming language with minimum commitment to syntax has an advantage. People can experiment more cheaply and in my experience refactoring lisp code is a lot easier than more verbose or inflexible languages. Migrating from lisp to other languages also seems to be a relatively easy path to follow too (I laugh, but I'm serious - this is a useful property when prototyping). But that isn't very powerful compared to a problem domain expert working in a language they like. If someone doesn't like lisp then they shouldn't use it and they'll probably do well.
