Any time that time travel is mentioned (and it will be many times today), the conversation gets Godwined pretty quickly into a discussion on the feasibility of killing Hitler before he begins his reign of terror. Rob Manuel of b3ta posits the idea that it’s been done, or at least attempted, many times. Out of 27 unsuccessful attempts at assassination (that we know of), how many of them could be the result of a future in which time travel is possible? And at what point did these future people figure out it couldn’t be done?
