As computer hardware and software becomes ever more powerful, they find ways to match and then exceed many human abilities. One point of superiority that humans have stubbornly refused to yield is tuning musical instruments. Pythagoras identified the precise, mathematical relationships between musical tones over 2,000 years ago, and modern machines can beat out any human when it comes to precise math. So why aren’t computers better than people? The professional tuner does have one incontrovertible advantage: a trained human ear.

Ever wondered how you were supposed to keep up with the never-ending stream of content and data in your life? Not to worry, the elves of the Internet are busy at work, creating everything from magical little algorithms that automatically execute basic tasks to sophisticated utility apps that run in the background, taking care of all the minutiae in your daily life. Forget about hiring a personal assistant, you can “hire” off-the-shelf algorithms and digital apps that do all the heavy lifting for you. If that doesn't work, just ask Siri. Your life is an algorithm, your brain is an operating system, now go get some sleep.

Indie movie makers can be a strange bunch, pushing the envelope of their craft and often losing us along the way. In any case, if you’re going to produce something unintelligible anyway, why not let a computer do it? Eve Sussmam and the Rufus Corporation did just that. She and lead actor Jeff Wood traveled to the Kazakhstan border of the Caspian Sea for two years of filming. But instead of a movie with a beginning, middle and end, they shot 3,000 individual and unrelated clips. To the clips they added 80 voice-overs and 150 pieces of music, mixed it all together and put it in a computer. A program on her Mac G5 tower, known at Rufus as the “serendipity machine,” then splices the bits together to create a final product.
