There have been many instances in our history where someone warned us about something, but we didn't listen at all. It seems that before almost any major event, a doctor, scientist, or politician already knew the outcome, but was simply ignored. It seems to be a repeating pattern, so the question this Redditor asked sparked a lot of interest from internet users.
Many chimed in to share all sorts of stories that are very insightful and eye-opening. Perhaps reading through them will help us get some perspective on our world and see that having an open mind is a very good thing. It seems that in a lot of instances, great tragedies might have been avoided if only people listened to each other more.

H G Wells said he wanted his epitaph to be "I told you so. You damned fools!" In The Land Ironclads (1903) he had written about a stalemated war fought by trench warfare that was broken by the invention of tanks, predicting what would happen in WW1. In The War in the Air (1907) he predicted how airplanes would be used in war, including aerial bombardment of cities, and saw his predictions come true in WW2.
