One area Morse code is popular is using limited radios. Morse code works well with tiny (phone sized), low power radios. There is challenge called SOTA where hike to top of mountain and make contacts. It is much easier to take small radio and Morse paddle than the bigger radios needed for voice. There are low-power data modes, but then have to carry computer along and deal with software.
