The use of Morse or any other 'tool' is dictated upon what problem(s) we're trying to solve using radio and then applying the appropriate technology (if available). For sending a list of refugee names, their medical needs, next of kin and etc. : use digital IF ABLE. Zero question there, and that's how we set-up our Emergency Operation Center for my surrounding counties. OTOH, if the problem to be solved is checking in with people, situation reports, advisories and etc., withOUT the overhead of a computer, then Morse (CW) fits quite nicely. Basically as pointed-out, if it requires basic communication, or even passing short messages (think SMS texting on steroids) under rough conditions, then Morse is a great tool when/if you require the minimum of Size, Weight & Power consumption.
If I were in my house, I absolutely use WINMOR (e-mail over radio) and some of the modes in the FLdigi program, because I can keep a laptop alive here. I did the same when I was a sailboat cruiser, using e-mail over radio and etc. for my corrospondence as well as my weather (with back-ups). However, if you do not have commercial power and/or if manpacking, or even vehicular mobile, CW beats voice (we all know that) for reliability and saves me having to keep a laptop alive.
Different tools for different jobs.
Again, lists, files and imagery - all handled by WINMOR and other digital modes. JIC, primitive, but easily supportable in the field: Morse. Everyting that I have a computer glitch, or an MS update that causes a problem for my laptop and etc. I realize that I am glad that I am conversational in Morse.
>>> As WA4STO can EASILY testify (I am not qualified to speak for him) being able to handle message traffic is a skill to practice on TOP of basic Morse fluency. There are specific methods for handling message traffic which takes it from casual -doing a Buddy a favor- to professional quality, correcting errors ('getting fills') and etc. which the average ham has never used and probably never even heard of. A maritime Morse operator would be an expert in such things. These traffic handling methods can be learned.
Nothing like having a good Sparkie ashore or aboard whether it's digital or Morse.
