The machine that invents

Technically, Stephen Thaler has written more music than any composer in the world. He also invented the Oral-B CrossAction toothbrush and devices that search the Internet for messages from terrorists. He has discovered substances harder than diamonds, coined 1.5 million new English words, and trained robotic cockroaches. Technically.

"His first patent was for a Device for the Autonomous Generation of Useful Information," the official name of the Creativity Machine, Miller said. "His second patent was for the Self-Training Neural Network Object. Patent Number Two was invented by Patent Number One. Think about that. Patent Number Two was invented by Patent Number One!"

On Christmas Eve 1989, Thaler typed the lyrics to some of his favorite Christmas carols into a neural network. Once he'd taught the network the songs, he unleashed the Grim Reaper. As the reaper slashed away connections, the network's digital life began to flash before its eyes. The program randomly spit out perfectly remembered carols as the killer application severed the first connections. But as its wounds grew deeper, and the network faded toward black, it began to hallucinate.

"Its last dying gasp was, 'All men go to good earth in one eternal silent night,'" Thaler said.
