I am old enough to have used a CADR Lisp Machine (which fittingly exposed me not only to the high-voltage Zetalisp language, but the high-voltage CRT electronics, as the monitor was lacking an enclosure) . Most of my subsequent experience (sadly) has been in C/C++. Perhaps of interest to this list is the contribution Lisp programmers made in birthing non-player-characters for
networked simulations/games. A pity no-one has ever told the tale (you will be hard-pressed to find any details whatsoever on the Lisp contribution).
My current endeavor integrates new Common Lisp code with complementary open source software. Worse may not really be better, but it seems to be a lot more widespread.
