Lisp machines were big in the 80s. They died with the AI boom. They're not going to take off again any time soon because Lisp as a platform is no longer nearly as important as it once was. The ability to target Unix/Windows, and the ability to run software to run and interact with software targeting Unix/Windows, is too important to let novel platforms really take off. There are 'Java machines,' for example, which are commercially viable so I understand, but how common are they?
