Ed Fries, co-creator of the Xbox, kicked off the day with a presentation that discussed why it's so futile to try and predict the future -- because, ultimately, the most important discoveries are often ones that are impossible to predict.
He presented a slideshow of what the Victorian era thought the future would look like: mail delivered to your house by airplane, luxurious personal submarines for all, and even cities covered by enormous roofs to keep the rain off.
"But," said Fries, "you never see a machine that runs itself. Something like a computer is just completely beyond comprehension."
He wrapped up by quoting computer scientist Alan Kay: "The best way to predict the future is to invent it."
