I'm going to apologize immediately since this is going to be a subjective question.
After reading an article about the new words added to the English language, noticing a trend in a few sci-fi books, and noticing the rising popularity in being a "grammar Nazi", I had an interesting thought.
Why haven't we changed the English language to a form that is easier to understand? All words spelled phonetically, simplified sentence structure, confusing elements removed, etc.
An example of this is science-fiction is in the Ender's series novels by Orson Scott Card where the English language has evolved to what is known as Common.
Bean responds: "I speak common, not English, and in common there is no such word as 'whom'".
I think this would be a great step forward!
