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."
