Telepathy? Since ours is the age of information explosion, with telepathy instead of having our colleagues need to explain everything to us, we can better understand each other and gain agreement. Instead of losing the meaning we want to convey from the inherent ambiguous nature of words, we can communicate the idea the closest possible way.
At present, for example there seems to be so many religions. One might wonder if they're all referring to the same things except using different words. If various groups and communities can communicate in telepathic ways then, words would not be needed; intuitive understanding becomes a given.
