You know what goes in, and you know what comes out. But you don't know what's inside. That's what black boxes are about. [Sexy female vocalist] I want to know. I want to know. I need to know. No, just let it go. Let it go. But I need to know. Can't let it go. [Robotic voice] System architecture. System architecture. [Talk-sung sardonic, dry, monotone male vocalist] Jeannie wants a genie. And Jerry wants one too. You can pay me a billion dollars. But I won't make one for you. I'll tell you how it's done, And pay yourself to build you one. Robots building robots—that's how it's done.

Don't let it go. Don't Let it go. I need to know. Can't let it go. [Robotic voice] System architecture. System architecture.
