I've used the ice breaker, "Would you rather go forward or backward in time?" for students for years! Students almost always say forward. They want to see how their lives will turn out, or what they might become. I always wonder if seeing the future would actually provide opportunities to change the trajectory of your life, or if future you somehow knows that you came to the future to see your future self, and the whole debacle is already factored into the bonkers algorithm of time.
I usually say I'd go backward- mostly because I'd want to go back to the 90s and buy some stocks. I'd love to be an early investor in a little web-based bookstore called Amazon, or a shareholder in Apple, Inc, back when nobody had even dreamed of iPhones yet.
Really, though, I think it's too dangerous either way. As I'm reading 11/22/63, there are just too many logistical questions. Could you accidentally wipe yourself out of history? Or clone yourself, so a younger you and older you exist on the same plane, aging in parallel until one suddenly disappears into time?
I hate to buy into the cliche "Everything happens for a reason," but I'm beginning to think it's better to leave the past alone and work on trying to influence the future from where we are right now.
