Must Time Travel Change History?

Perhaps the most common trope in time travel stories is the accidental (or deliberate) changing of history by a time traveler, and the attempt to set history "right" again. It makes an exciting story, but can we do something different with time travel without a deus ex machina?

Connie Willis, Bill Cherf, Thea Hutcheson(M), David Kilman, Sam Knight, Deena Larsen


4-5pm                             Rampart

The Structure of Storytelling and the Mind of Humans

Across all human cultures and times, the stories we tell all feel the same. The themes and cultural references change but the structures don't, with some exceptions. Is this rooted in our brains and what it means to be human? Would aliens tell stories in the same way?

Mike Brotherton, Connie Willis, David Boop(M), Sarah Hoyt, Thea Hutcheson, Laurey Patten


4-5pm                             Breckenridge

The HBO Effect - Must Fantasy be all Sex, Gore, and Politics now?

It's been long known that sex and violence sells, but ever since the HBO adaption of Game of Thrones appeared it seems the dial has been turned up to 11. Now most new televised science fiction and fantasy shows are sagas of violent politics, gushers of blood, and extreme sex. Will good taste and restraint ever prevail again?

Cyberpunk, Steampunk - now Feypunk?

It's alway fun to take our real world and twist it around. We've done that with the near future with Cyberpunk, our near past with Steampunk, and now we're doing it with our current times and fey creatures (elves, vampires, werewolves, and assorted others). Does that mean we're now doing "feypunk"? What does this "punk" thing mean anyway and what's the next new punk coming?
