Earlier quoted context omitted.
I will still say that lacking the ability to communicate via a particular medium is not the same as lacking social skills. My inability to send messages via Morse code over telegraph lines doesn't mean that I lack social skills.
So if a skilled telegraph operator handed you a message including the word "naloopen" you would know what that means? There was not just one but several forms of telegraphese developed. A conversation held entirely in brief dots and dashes has a substantially different flow to it than say typing out a message on an internet forum, which in turn is nothing like how one would communicate with a 5 second fleeting video…
To your point, if a telegraph operator handed me a message I didn't understand, I could just say, "Hey, I don't understand this message. Can you explain it to me?" because that is social skills.
