I think there are two (at least) sorts of programmers, the systems people and the lisp people. Sometimes you get both kinds in the same person but that tends to be rare (and awesome, I've employeed several of those, they were magic). I'm a systems guy. I've played with lisp, even wrote a tiny lisp (haven't we all?), tried to get to like it and utterly failed. All sorts of smart people I knew in my career loved lisp, sneered at any other language, tended to think in ASTs, etc, etc. I definitely felt inferior and tried to like lisp but just never got what was so neat about it. For good reason, I think. Nobody has written a serious operating system, or a serious $BIG_PROJECT in Lisp. Not one that has been commercially successful, so far as I know. I know there were attempts but all those attempts failed. Why? Performance I think. C performs far better even though it is, in the eyes of lisp people, far more awkward to do things. I can't tell you the number of times I've heard "If we were using Lisp we'd be done by now". 100's, 1000's. What I have never heard is "I recoded this pile of C in lisp and it's 10x faster". I think the thing is that lisp programmers were optimizing for speed of coding and C programmers were optimizing for speed of execution. So I suspect that Franz Lisp was mostly lisp people who happened to be using Unix. But I wasn't at Berkeley so what do I know? --lm
