Communication is an operation to share some thought or idea with the others. It is having something common. Of course, in CW communication, we use Morse code for the communication tool of symbol.
The message of communication could be various, from simple data, numbers or the model names of radio etc in concrete forms to our thoughts or feelings in abstract forms. As personal communication, CW QSO would give us pleasure when the message is concerned about the latter, that is, when we share thoughts or feelings with the others.
How often do we share those things with the others in CW communication? If CW communication loses this essential part, I believe, it won't last too long. I am afraid the trend of CW communication is just having concrete data with the others. It won't make young people fascinated with CW since it won't make any pleasure in communication.
