LLMs are surprisingly good at reading Morse code. Some time ago I pranked my flatmate. I installed a wifi switch in the wall and then wrote a script to convert text to Morse code and send the code with a slight delay through his lamp. I also built a website to do some legend-building to make him believe a ghost is haunting our apartment. He sent a video of the flickering lamp to chatGPT and it correctly deciphered it. We had a good laugh when I revealed the prank to him.
