Lisp is shit for AI programming

If Lisp is so great for AI, how come IBM Watson's core natural-language processing and voice recognition subsystems are written in C++ and some assembly language for SIMD vector processing, and its distributed computing infrastructure is tied together using Java and the Apache Hadoop framework?

I'd say Lisp is big piece of the rotten puzzle when trying to decide what was responsible for the AI winter and in creating perceived negative connotations for the AI industry and robotics in general.

Things like IBM Watson, Kinect (you can joke around, but there's some amazing stuff in there), and so on are finally starting to put an end to the AI winter. And they sure as hell aren't written in Lisp or esoteric languages like Haskell, Scala, Erlang, etc.

Seriously, if it's Lisp, it's shit.

Hahaha, please. Is that all you Lifthp degenerates could come up with? A bunch of lousy excuses? There's no such thing as a team of competent Lifhpers. Lifhpers are naturally prima-dona lone hacker types who would never work together on anything of importance. They're all too consumed with their toy projects.

Real AI work is done by real programmers using real languages like C++.

Face it. Lifhp is forever in the gutter.
