I'm very pleased to announce that I'll be giving a presentation at TEDxBoulder on September 24 this year. TEDx events are independently organized from TED, but feature the same sorts of talks: inspiring, entertaining, and designed to help make the world a better place. My topic? Trying to make the world a better place by preventing an asteroid impact from making it a far, far worse place. The other talks look pretty interesting, including one from Kimbal Musk, Elon Musk's brother, and also from Jake Nickell, co-founder of the Threadless t-shirt company. I think this will be a very cool evening. Tickets are on sale now but I hear it's filling up quickly, so if you're in the Boulder area and want to attend, better hurry!
