Morse code is not dead yet. The headlines a few years ago referred to the use of morse as a primary means of ship-to-shore communication and the two five-minute periods each hour when radio traffic was kept to a minimum so as to keep the airwaves free for emergency traffic.
The armed forces still use morse code by radio and light. The latter is regularly used by warships for line-of-sight communication. It has the advantage of being directional (with a proper signalling lamp) and un-jammable. As a watch keeping officer I was expected to be able to send and receive at 5 words per minute, a pathetically low speed compared to our experienced tactical signalmen. With a lightweight lamp all you see was a continuous flicker of light.
