Erasing that initial bad impression may be a generational thing. Even heroin goes through cycles where a new generation comes along that hasn't seen anyone die of heroin, they make heroin cool for a while, and then the horrifying results inoculate the culture against the idea that heroin is cool for another fifteen or twenty years. Lisp will get another chance, and it can afford to wait.
Also, I think next time around it won't be Lisp, the universal solution. It will be a Lisp. It might not even be called Lisp. It might be called "Clojure" or something odd like that ;-)
More and more I hear people 'they've been doing this in lisp all along' so I make a naive guess that in the future lisp genes will reappear in more favorable settings and won't get dismissed as they were before. It's already happening as for gc's and closure right ?
