Everyone likes to think that they're smart. We all consider ourselves geniuses in our own right, and you very well might be one. Just as much as people love being seen as geniuses, however, we also hate being called out when we're wrong. The ego can't really take that hit.
Don't feel bad about it, though, because some of the world's greatest minds made bold predictions about the future that turned out to be utterly false.
