Lisp succeeded after being on life-support, much like Apple. Take Clojure, for instance; or Hacker News, a major tech industry hub which is written in a lisp. Or:

Guy Steele (Java spec coauthor):

"And you're right: we were not out to win over the Lisp programmers;

we were after the C++ programmers. We managed to drag a lot of

them about halfway to Lisp. Aren't you happy?"

(http://people.csail.mit.edu/gregs/ll1-discuss-archive-html/msg04045.html)

Yukihiro Matsumoto (Ruby creator):

"So, Ruby was a Lisp originally, in theory. Let's call it MatzLisp

from now on. ;-)"

(http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/179642)

Douglas Crockford (Yahoo! Javascript architect):

"Lisp in C's Clothing

"JavaScript's C-like syntax, including curly braces and the clunky

for statement, makes it appear to be an ordinary procedural

language. This is misleading because JavaScript has more in common

with functional languages like Lisp or Scheme than with C or Java."

(http://www.crockford.com/javascript/javascript.html)

Brendan Eich (Javascript creator):

"As I’ve often said, and as others at Netscape can confirm, I was

recruited to Netscape with the promise of “doing Scheme” in the

browser." [Scheme is a lisp.]

(http://brendaneich.com/tag/history/)

But I certainly don't mean to get into a flamewar about who wields the bigger instrument — this hypermasculine industry is quick to label ideas as winners and losers, based on what happened in the market. (When I gave a talk about "strange passions" in computing last month, the organizer tried publicly goading me into saying that my instrument of choice was a bigger phallus than the last guy's. I refused, sending me off into a tangent that my personal drives were my own; another person may find that playing another instrument may get them into the Zone better.)

And about AI, anyone interested in philosophy or psychology might enjoy reading the thoughts of people like Minsky. AI is very misunderstood. Being in a pre-Galilean phase doesn't mean that the intellectuals of the day are failures. (Is Chomsky a failure, because he says that linguistics hasn't yet had its Galileo?)

BTW, the Strange Loop videos are trickling online: http://www.infoq.com/presentations/Simple-Made-Easy

All the best,

Tj

They used to be a fun read, especially since (by my reading) the guy used to run circled around McCarthy. McCarthy made great contributions to Computer Science, but I am glad that his (and Minsky’s) brand of AI, as well as Lisp, failed by and large (though these days there is a significant renewal of functional languages). I know it’s a stretch, but I think there is an interesting contrast that can be drawn between the work of the two greats who died in the last few days: Ritchie and McCarthy. C and Lisp. Unix/IP (and the underlying methodology) and strong AI, US and Japan. I am not the person for it (for one thing I am clearly biased :-)).
