Science fiction writer and physics professor Gregory Benford was the Guest of Honor at Fencon 2008. On several occasions during convention he shared his thoughts on topics such as American dominance in the world and its role to play in the technological future. Having been in science fiction fandom for four decades, Benford is proud of American science fiction and fandom influence on the world, which he puts in such blunt terms as "We own the future". At the same time he acknowledges that the future is not all rosy, and that science fiction may be the proverbial canary in the coal mine, signaling of darker times to come. Benford's keynote speech on Saturday was the problems facing the world and what can be done about them. Of those, global climate change was the most significant issue. He assured us that whatever is being done to counter it isn't working, because global warming is typically viewed as a moral problem (excessive consumption), when it needs to be seen as an engineering problem. To that end he proposed an unconventional -- or perhaps little known -- approach. At the end of his speech he spent some time on space travel and overpopulation.
Gregory Benford also appeared in the "Science -- fact or crap?" game at Fencon, where two teams of players competed regarding their knowledge of science facts. Read more about it in my blog.
