> In The Amazing Digital Circus (episode 8, "hjsakldfhl"), when Kinger opens the terminal to try to reset Caine, you can see that Caine (a creative AI built in 1996) is programmed in Lisp. The file is literally named Caine-core.lisp.

Nice touch. Explains how Caine returns in episode 9: Lisp continuations allow for graceful error recovery.
