I never used email growing up. Real time chat has always been a much more effective method of communication. Email just causes confusion as people misinterpret questions and then write long-winded answers to the question that they misunderstood resulting in a waste of time for both parties. Iterative back and forth communication is key to figuring out an issue. Email does not work.
Email is the most efficient way to communicate if one can communicate clearly. It is a way straight to hell if one can't. It is a tool. It can be used. Or abused.
People who don't read comfortably don't like email. (They also don't like closed captioning.) We can't organize the workplace around their preferences, however.
Email needs to die.
