Well, people who make memes about Morse Code never specifically write Morse within their memes. They just want clout.P.S did you say [actually can you type morse code?]
People who make memes about morse code; You can't make a meme about a language compromising of noise sequences and pauses related to everyday objects, like tapping a pen or beatboxing because you will only have one length of sound, which makes it impossible to replicate, or even attempt to do so, as morse is made of 2 beats, each being at least 500ms separated from each other. Even if you get past that, you still have to be insanely lucky just to make it sound like "I'll use cotton candy to raid you!" etc. In conclusion, those memes may be good for reeling in views and upvotes, but you will not see them in action, and are only a fantasy.
