Morse is not all in the past tense, as you write. I have learnt it, a bit, for amateur radio, where it is still used. There are lots of wee applications for it too, like showing status messages on a small electronic device using a single LED. There have been times I have wished more people know it, for example for communicating with light accross a mountain valley, or communicating underwater.
